NVIDIA closed a six-year gap in its cloud gaming service on August 18, 2026, when GeForce NOW went live inside Mozilla Firefox for the first time. The update, confirmed jointly by NVIDIA and Mozilla, lets Firefox users on Windows stream more than 2,000 PC games directly in the browser, no downloads, no Chromium engine, and no separate app required. It closes out one of the longest-standing complaints in cloud gaming: that NVIDIA’s flagship streaming service only worked properly on Chrome, Edge, Safari and Opera GX, leaving Firefox’s roughly 3.3% of the global browser market locked out of native support.
The move lands in the middle of a wider scramble among cloud gaming platforms to strip away friction. Amazon folded Luna into its Prime Video app earlier this summer, Microsoft is testing an ad-supported way to stream owned games straight from a browser, and NVIDIA itself just finished rolling Blackwell RTX 5080-class hardware out to most of its data centers worldwide. Firefox support is a smaller headline than a GPU upgrade, but it answers a question NVIDIA has dodged for years: why build a service that promises to run anywhere, except in the browser roughly one in every thirty PC users already has open.

Quick Facts: GeForce NOW on Firefox
- Launch date: Firefox for Windows became an officially supported GeForce NOW browser on August 18, 2026, timed to the Firefox 154.0 release.
- Game library: NVIDIA and Mozilla say Firefox users can stream more than 2,000 PC games through GeForce NOW.
- Top streaming quality: GeForce NOW Ultimate subscribers can stream at up to 1440p resolution and 120 frames per second in the browser tab.
- Platform scope: Windows only for now — Firefox on macOS, Linux, Android and iOS can browse the catalog but cannot stream yet.
- Pricing: Unchanged by the Firefox launch — free tier, $9.99/month Performance, $19.99/month Ultimate, each capped at 100 hours of monthly play.
NVIDIA Brings GeForce NOW to Firefox After Years of Requests
Mozilla’s own announcement did not bury the wait. “Gamers have asked for GeForce NOW support for years,” the company wrote in its August 18 blog post confirming the rollout. “Today, NVIDIA made it official, opening up GeForce RTX-powered play to Firefox on Windows.” The post frames the update as the product of sustained engineering work between the two companies rather than a routine browser-compatibility patch, and both firms timed the release to Firefox 154.0, whose official release notes list Firefox on Windows as “now a supported browser for NVIDIA GeForce NOW, letting users stream supported PC games directly in the browser.”
Firefox previously sat on NVIDIA’s own release-notes page in the opposite column: as of July 28, 2026, NVIDIA’s release-highlights page explicitly listed Firefox and Opera among browsers that “do not support streaming” on play.geforcenow.com, though users could still browse the catalog. That changed within three weeks. NVIDIA’s Director of GeForce NOW, Andrew Fear, put the update in blunt terms: “Firefox earned its place on our list of supported browsers by delivering the first-class experience GeForce NOW players expect,” he said, adding, “We set a high bar for browser support, and we’re excited to welcome Firefox — giving millions of Firefox fans a new way to stream the games they love.”
Mozilla’s promotional page for the launch keeps the pitch simple. “Firefox is ready to play with GeForce NOW,” the headline reads, followed by the line, “Now you can stream the PC games you already own, right in your browser.” A third line drives home the pitch that has defined cloud gaming marketing since the category existed: “Nothing to install.”
The Announcement: What NVIDIA and Mozilla Confirmed on August 18
The rollout is narrower than “Firefox support” might suggest, and both companies were specific about the boundaries. Support currently covers Firefox on Windows only, not macOS or Linux builds of the browser, and not Firefox on Android or iOS. Within that scope, GeForce NOW Ultimate subscribers can stream at up to 1440p resolution and 120 frames per second directly in the browser tab, according to The Verge’s coverage of the launch, which also notes the update makes Firefox “GeForce Now’s first non-Chromium browser” to receive official support.
That non-Chromium detail matters more than it looks. Chrome, Edge and Opera GX all run on the same Chromium rendering engine and share the same underlying WebRTC and media-decoding stack, which means adding support for one is close to adding support for all three simultaneously. Firefox runs on Mozilla’s independently developed Gecko engine, so bringing GeForce NOW to Firefox required NVIDIA and Mozilla engineers to validate an entirely separate browser codebase for low-latency video decoding, input handling and DRM-protected streaming, rather than reusing work already done for the Chromium browsers. Engadget’s report on the launch notes that Firefox now joins “Chrome, Edge, Safari and Opera” as officially supported browsers, completing the set of the five most-used desktop browsers on the market.
Games remain tied to the libraries subscribers already own. Nothing about the Firefox launch changes GeForce NOW’s core model: users still need an existing account on Steam, Epic Games Store, Ubisoft Connect, GOG or Xbox, and GeForce NOW streams the game they already purchased there rather than selling or hosting games itself. Coverage circulating across tech outlets this week reiterated that Ultimate members keep access to connected libraries across Steam, Epic, GOG and Xbox Game Pass regardless of which supported browser they launch from.
How Firefox Streaming Works — and What You Need to Try It
Getting started does not require installing an extension or enabling a hidden flag; NVIDIA and Mozilla built the feature to work out of the box on a current release of Firefox for Windows. Anyone hitting playback issues on an older Firefox build should still check the two settings most likely to affect video-streaming performance in any browser, cloud gaming included:
Open Firefox → type about:config in the address bar → accept the risk warning
Search: media.hardware-video-decoding.enabled → confirm it is set to true
Search: gfx.webrender.all → confirm it is set to true
Restart Firefox, then go to play.geforcenow.com and sign in with your NVIDIA accountFrom there, the flow mirrors what Chrome and Edge users have had for years: sign in, link a game-store account if it isn’t already connected, pick a title from the library, and join the queue. Free-tier users are placed behind a standard queue with hour-limited sessions; Performance and Ultimate subscribers get priority access. NVIDIA has not published Firefox-specific queue-time data, so early adopters should expect wait times comparable to what they’d see on Chrome at the same time of day, on the same tier.
Troubleshooting Firefox Streaming: Fixing the Most Common Issues
Official support doesn’t guarantee every session runs smoothly on the first try. Because Firefox’s Gecko engine handles hardware acceleration, tracking protection and extensions differently than the Chromium browsers GeForce NOW has supported for years, a short checklist of Firefox-specific settings resolves most playback issues that have surfaced since the August 2026 rollout, before they need a support ticket:
- Black screen or stream won’t start: Recheck
media.hardware-video-decoding.enabledandgfx.webrender.allinabout:config, then fully restart Firefox rather than just reloading the tab. - Choppy video or dropped frames: Switch from Wi-Fi to a wired ethernet connection where possible. Cloud streaming is more sensitive to latency spikes and packet loss than to raw bandwidth.
- Stream freezes or disconnects mid-session: Firefox’s Enhanced Tracking Protection and third-party ad blockers can interfere with the WebRTC connections streaming depends on. Test play.geforcenow.com in a Private Browsing window with extensions disabled to isolate the cause.
- Controller not detected: Connect the controller after the stream has fully loaded, and confirm Windows itself recognizes it before opening Firefox.
- Audio out of sync: Refresh the browser tab rather than restarting the whole session; a partial reload typically clears audio-sync glitches without losing your spot in the queue.
Most of these fixes trace back to one cause: Firefox doesn’t share the same WebRTC and hardware-decoding defaults as Chromium, so a handful of settings Chrome and Edge users never have to touch occasionally need a manual check on Firefox. NVIDIA has not published a Firefox-specific troubleshooting guide separate from its general GeForce NOW support documentation, so the checklist above draws on the same underlying settings the browser rollout itself relies on.
Why It Took Six Years to Get Here
GeForce NOW launched in public beta in October 2015 and moved to a paid public service in February 2020, according to background compiled on the service’s history. Chrome-based browser support arrived years before Firefox, and NVIDIA never gave a public technical reason for the gap beyond general engineering prioritization. The likeliest explanation is the one implied by the scale of Chromium’s install base: Chrome alone accounts for the large majority of desktop browser traffic worldwide, and Edge and Opera GX both inherit Chromium’s codebase for free, so NVIDIA’s engineering return on supporting those three browsers was always going to outpace the return on a fourth, architecturally separate browser with a shrinking user share.
That calculus has visibly shifted. Firefox’s worldwide market share sat at 3.34% across all platforms and 6.51% on desktop specifically in July 2026, according to StatCounter’s global browser tracking, a share that has been sliding for years but appears to have leveled off in 2026 after touching lows near 2.26% earlier in the year. A shrinking, stabilizing user base is not the obvious trigger for a new engineering investment, which suggests NVIDIA’s real motivation runs closer to what Fear’s quote implies directly: closing a support gap that had become a recurring, visible complaint from a vocal segment of PC gamers, regardless of exactly how large that segment is.
GeForce NOW Pricing Tiers: What Firefox Users Actually Get
The Firefox launch changes nothing about GeForce NOW’s subscription structure. NVIDIA still runs three tiers in the US: a free tier with one-hour sessions and standard queue priority, a Performance tier (renamed from “Priority” earlier this year) at $9.99 a month with six-hour sessions and 1440p/60fps streaming, and Ultimate at $19.99 a month with eight-hour sessions and access to the newer Blackwell RTX 5080-class server hardware NVIDIA finished rolling out across most of its first-party data centers earlier this year. Since January 1, 2026, both paid tiers carry a 100-hour monthly playtime cap, with additional 15-hour blocks available for $2.99 on Performance and $5.99 on Ultimate.
NVIDIA held that $19.99 Ultimate price flat through the entire Blackwell hardware transition, even as rivals moved their own cloud gaming pricing in both directions during the same stretch — Microsoft cut Xbox Game Pass Ultimate’s price after a backlash to an earlier increase, and Amazon has been testing folding Luna into Prime Video rather than raising its standalone price. Firefox users landing on GeForce NOW for the first time step into that same pricing structure and the same 100-hour cap, with no separate “browser tier” or introductory pricing tied to the Firefox launch specifically.
GeForce NOW Browser Support Timeline
| Browser | Engine | Support Status (Aug 2026) | Max Streaming Quality (Ultimate) |
|---|---|---|---|
| Google Chrome | Chromium | Supported (longest-standing) | Up to 4K/120fps (desktop app parity) |
| Microsoft Edge | Chromium | Supported | Up to 4K/120fps |
| Apple Safari | WebKit | Supported | Up to 1440p/120fps (macOS) |
| Opera GX | Chromium | Supported | Up to 4K/120fps |
| Mozilla Firefox (Windows) | Gecko | Supported starting Aug 18, 2026 | Up to 1440p/120fps |
| Firefox (macOS, Linux, Android, iOS) | Gecko | Not yet supported for streaming | Catalog browsing only |
The table underscores how incremental the Firefox win actually is next to what remains outstanding. Firefox on Windows is now covered, but Firefox on macOS, Linux, Android and iOS is not, and NVIDIA has not committed to a timeline for extending support to those builds. Given how long the Windows version took, a broader Firefox rollout across platforms should not be assumed to arrive quickly.
How GeForce NOW Compares to Xbox Cloud Gaming, Amazon Luna and Boosteroid
NVIDIA is not the only company fighting over which browsers and devices can run a cloud gaming session without a native app. Microsoft’s Xbox Cloud Gaming already supports browser play across Windows, Android, ChromeOS, iOS, iPadOS and Mac, bundled inside a Game Pass Ultimate subscription that costs $22.99 a month, and Microsoft separately launched a free, ad-supported tier in 2026 capped at five hours of streaming per month for players who already own qualifying games. Amazon Luna+ costs $9.99 a month in the US, per Amazon’s own published pricing, and supports Chrome, Edge and Safari but has never added Firefox streaming support. Ukraine-based Boosteroid, a smaller but fast-growing player in Europe, prices its Ultra tier around €12.89 a month (roughly $14.80) and Ultra Pro around €14.89 a month (roughly $17.10), undercutting GeForce NOW Ultimate on price while running on less powerful server hardware.
None of GeForce NOW’s three closest competitors currently support Firefox for actual game streaming, which briefly makes NVIDIA’s service the only one of the four to run natively in a non-Chromium, non-WebKit browser on any platform. That’s a narrow technical distinction most subscribers will never notice day to day, but it’s a meaningful one for the sliver of PC gamers who have stuck with Firefox on principle, for privacy reasons, or simply out of habit, and who previously had to switch browsers or install a separate app just to stream a game they already owned.
Cloud Gaming Platform Comparison: Pricing and Browser Support
| Service | Entry Price (Paid Tier) | Free Tier | Browsers Supported | Monthly Hour Cap |
|---|---|---|---|---|
| NVIDIA GeForce NOW | $9.99/mo (Performance), $19.99/mo (Ultimate) | Yes, 1-hour sessions | Chrome, Edge, Safari, Opera GX, Firefox (Win) | 100 hrs (paid tiers) |
| Xbox Cloud Gaming | $22.99/mo (Game Pass Ultimate) | Yes, ad-supported | Chrome, Edge, Safari, Windows/Android/iOS/Mac apps | 5 hrs (free tier) |
| Amazon Luna+ | $9.99/mo | Limited free channels only | Chrome, Edge, Safari | No published cap |
| Boosteroid | ≈$14.80/mo (Ultra), ≈$17.10/mo (Ultra Pro) | No | Chrome, Edge, Safari | No published cap |
Read across the row, GeForce NOW’s Firefox move doesn’t change its position on price. It’s still the most expensive Ultimate-style tier of the four on a straight monthly basis, ahead of Boosteroid and roughly double Luna+, but it now offers the broadest browser reach of any service in the category by a clear margin.
Market Impact: A Small Win for Firefox’s Shrinking Browser Share
Firefox’s global browser share has been in a long decline for close to a decade, falling from double-digit territory in the early 2010s to the 3.34% (all platforms) and 6.51% (desktop) figures StatCounter reported for July 2026. Mozilla has spent 2026 framing recent readings as evidence the slide is leveling off rather than reversing, and a high-profile partnership with the biggest name in cloud gaming is exactly the kind of feature announcement that supports that narrative, even if it’s unlikely to move the market-share needle in any measurable way on its own. Browser choice is sticky, and a single new supported use case rarely pulls users away from Chrome’s roughly two-thirds global share.
The more realistic read is that this is a retention play for Mozilla and a completeness play for NVIDIA. Firefox loyalists who were already considering switching browsers specifically to use GeForce NOW now have one fewer reason to leave; NVIDIA, in turn, can advertise “works in every major browser” without an asterisk. Neither company is treating this as a growth lever in public statements, and the muted rollout, a joint blog post and a browser release-notes entry rather than a Gamescom-style keynote moment, reflects that.
Historical Context: Cloud Gaming’s Long Fight Against the Browser
Browser-based game streaming has been a stated goal of cloud gaming since Google’s short-lived Stadia pitched “click a link, start playing” as its core differentiator before shutting down in 2023. NVIDIA has taken the opposite, slower path: GeForce NOW launched with a native app requirement and added browser support incrementally over its ten-plus-year history, prioritizing Chromium browsers first because of their shared engine and dominant market share. Xbox Cloud Gaming followed a similar trajectory, starting as an Xbox-app and console-first product before Microsoft opened a public web-browser preview in January 2026 and expanded it through the year. Amazon Luna launched as a standalone browser-and-app hybrid from day one in 2020, giving it an early lead on browser flexibility that it has since partly given up by merging into Prime Video.
Seen against that backdrop, NVIDIA’s Firefox announcement isn’t a leap forward so much as the closing of the last real gap in an already-long list of supported browsers. The company that once needed a dedicated app to stream a single game now supports every major browser engine in active use, Chromium, WebKit and Gecko alike, on the platform where most of its subscribers actually play: Windows PCs.
Why NVIDIA Is Racing to Remove Every Barrier to Play
NVIDIA’s cloud gaming business exists inside a company whose center of gravity has shifted hard toward AI data center revenue, where quarterly numbers now run into the tens of billions of dollars. GeForce NOW is a comparatively small, subscription-driven line next to that, which makes friction-removal a cheap, low-risk way to defend and slowly grow a service that still matters strategically: it keeps NVIDIA’s brand and RTX technology in front of PC gamers who might otherwise never interact with NVIDIA hardware directly, particularly on laptops, Macs, Chromebooks and now a wider spread of browsers. Every barrier removed, whether it’s a new supported browser, a new supported device, or new server hardware, is a small, compounding argument for staying subscribed rather than buying a gaming PC or console outright.
That logic also explains why the Firefox launch skipped the fanfare NVIDIA reserves for hardware upgrades like the Blackwell RTX 5080 rollout. A new GPU generation is a headline event that justifies a keynote slot; a fourth browser engine is maintenance-grade infrastructure work that mostly matters to the subset of users it directly unblocks. NVIDIA treated it accordingly, routing the announcement through Mozilla’s blog and its own release notes rather than a press event.
What This Means for Steam, Epic Games and PC Ownership
GeForce NOW’s model has always depended on, rather than competed with, PC storefronts. Every game a Firefox user streams still has to be purchased on Steam, Epic Games Store, Ubisoft Connect, GOG or through Xbox Game Pass first; NVIDIA sells compute time, not games. That structure means the Firefox launch is a mild but real tailwind for Steam and Epic specifically, since it makes it marginally easier for a new category of user, people running Firefox on modest or aging hardware, to actually play games they buy on those storefronts without upgrading a PC. Steam’s own numbers show why that installed base matters: the platform set an all-time concurrent-user record of 42,042,778 players on January 11, 2026, a figure that gives some sense of the scale GeForce NOW is riding on rather than replacing.
For PC ownership more broadly, the Firefox update reinforces a trend that’s been building for several years: the browser, not the operating system or the hardware, is increasingly where “PC gaming” actually happens for cloud-first users. A Firefox user with a five-year-old laptop can now stream Blackwell-class RTX performance without installing anything beyond the browser they already have open, which quietly lowers the hardware bar for playing modern, demanding PC games to whatever a browser needs to run.
Five Predictions for GeForce NOW’s Next Moves
- Firefox expands beyond Windows within 12 months. NVIDIA and Mozilla’s public framing as a partnership, not a one-off patch, makes macOS and Linux Firefox support a logical next step, though Android and iOS face additional app-store and mobile-browser restrictions that could delay mobile support well beyond that window.
- The 100-hour monthly cap stays in place through 2026. NVIDIA introduced the cap on January 1, 2026, and has shown no public sign of reversing it; a new browser adds users, not server capacity, so the incentive to lift usage limits doesn’t change.
- Ultimate pricing holds at $19.99 through at least early 2027. NVIDIA kept that price flat through an entire GPU hardware generation change; a browser-support update is a far smaller cost to absorb and unlikely to trigger a price move on its own.
- Rival services add non-Chromium browser support within a year. Xbox Cloud Gaming and Amazon Luna both have the technical base to follow NVIDIA’s lead, and neither wants to be the last major cloud gaming platform without Firefox support once it becomes a checkbox feature reviewers compare.
- Browser-based streaming keeps gaining share of GeForce NOW’s total sessions. As more devices, operating systems and now browsers get native support, the case for installing NVIDIA’s standalone app weakens for casual and multi-device users, even if power users on a single dedicated PC keep favoring the app for marginally lower latency.
Expert and Industry Reaction
Public commentary on the Firefox launch so far has come almost entirely from NVIDIA and Mozilla themselves, rather than third-party analysts, reflecting how narrow a story this is next to a hardware launch or a pricing change. NVIDIA’s Andrew Fear framed the update as closing a credibility gap with the company’s own standards, telling Neowin that “Firefox earned its place on our list of supported browsers by delivering the first-class experience GeForce NOW players expect.” Mozilla’s messaging leaned on simplicity over technical detail, repeating across its landing page that streaming in Firefox means there’s “Nothing to install” and that users can “stream the PC games you already own, right in your browser.” Both companies’ language points toward the same audience: existing PC gamers who own games elsewhere and want one fewer app running in the background, not new players being pulled into PC gaming for the first time.

Frequently Asked Questions
When did GeForce NOW add Firefox support?
NVIDIA and Mozilla confirmed Firefox support for GeForce NOW on August 18, 2026, timed to the release of Firefox 154.0. Support currently covers Firefox on Windows only.
Does GeForce NOW work on Firefox for Mac or Linux?
Not yet. As of the August 2026 launch, streaming support is limited to Firefox on Windows. Firefox users on macOS or Linux can still browse the GeForce NOW game catalog but cannot stream through Firefox on those platforms.
What resolution and frame rate can I get on Firefox?
GeForce NOW Ultimate subscribers can stream up to 1440p at 120 frames per second through Firefox on Windows. Lower tiers stream at reduced resolutions and frame rates in line with their existing limits on other supported browsers.
Do I need to buy games through NVIDIA to use GeForce NOW on Firefox?
No. GeForce NOW streams games you already own on connected storefronts, including Steam, Epic Games Store, Ubisoft Connect, GOG and Xbox Game Pass. NVIDIA does not sell games directly through the service.
How much does GeForce NOW cost after the Firefox update?
Pricing is unchanged. GeForce NOW remains free with limited one-hour sessions, $9.99 a month for the Performance tier, and $19.99 a month for Ultimate, each subject to a 100-hour monthly playtime cap introduced on January 1, 2026.
Is GeForce NOW on Firefox better than the Chrome version?
NVIDIA has not published performance benchmarks comparing Firefox to Chrome for GeForce NOW streaming. Both are officially supported at the same subscription tiers, and any performance difference is more likely to come from local hardware acceleration settings than from the browser choice itself.
Why did GeForce NOW take so long to support Firefox?
NVIDIA has not given a detailed public explanation, but Firefox runs on Mozilla’s independently built Gecko engine rather than the Chromium engine shared by Chrome, Edge and Opera GX, which meant NVIDIA could not simply extend its existing Chromium-based streaming work to cover Firefox. Firefox’s declining global browser share, now around 3.34% across all platforms, likely also reduced the engineering priority relative to more widely used browsers.
Do Xbox Cloud Gaming or Amazon Luna support Firefox?
Not for game streaming as of August 2026. Xbox Cloud Gaming and Amazon Luna both officially support Chrome, Edge and Safari, but neither has added Firefox streaming support, making GeForce NOW the only major cloud gaming service currently supporting a non-Chromium, non-WebKit browser.
