NVIDIA has announced that its cloud game streaming service, GeForce NOW, now fully supports the Windows version of Mozilla Firefox. This means the vast community of Firefox users will no longer need to install a separate standalone application or switch to a different browser entirely – they can now play more than 2,000 PC titles directly within their browser of choice.
Breaking Chromium’s Dominance: Up to 1440p at 120fps
Over the past period, GeForce NOW has progressively added support for major browsers including Chrome, Microsoft Edge, Safari, and Opera. However, with the exception of Safari, nearly every Windows browser supporting the service to date has been built on the Chromium engine. Firefox’s inclusion therefore marks NVIDIA’s successful integration with an entirely independent web engine architecture.
According to official information from Mozilla, GeForce NOW Ultimate subscribers streaming through the Windows version of Firefox can now achieve resolutions up to 1440p paired with buttery-smooth frame rates reaching 120fps. Users need only update their browser to the latest Firefox 154 release and sign in through play.geforcenow.com to seamlessly stream their game libraries from Steam, the Epic Games Store, GOG, Xbox PC Game Pass, or Ubisoft Connect.
Months of Deep Optimization: WebRTC and Low-Latency Input
Mozilla also revealed that this support represents far more than simply flipping an access switch. Cloud gaming ranks among the most demanding stress tests a web browser can face – even a single millisecond of latency or a dropped frame can severely degrade the gaming experience.
To meet that bar, Mozilla and NVIDIA’s engineering teams conducted months of deep technical collaboration. According to details the Firefox team shared with the developer community, both companies undertook extensive low-level fixes and optimization work focused specifically on fullscreen Keyboard Lock, WebRTC streaming technology, Pointer Events, and hardware video decoding – ultimately meeting NVIDIA’s exacting standards for streaming quality.
While official support currently remains limited to Windows, the Firefox team confirmed that verification work for macOS and Linux platforms is actively ongoing, with the possibility of official support arriving in the future.
A Win for Both Gamers and the Browser Ecosystem
Bringing GeForce NOW to Firefox represents a strategic win-win for both NVIDIA and Mozilla.
For NVIDIA, expanding GeForce NOW’s device coverage sits at the core of its cloud gaming business growth strategy. In a market environment where high-end graphics card prices remain steep and the cost of upgrading PC hardware stays persistently high, lowering the barrier to entry is the most effective way to attract casual gamers or consumers without the budget for hardware upgrades.
Integrating with Firefox means NVIDIA has now filled the final missing piece among mainstream desktop browsers, further advancing its vision that any device with a web browser can become a gaming PC.
As for Mozilla, Firefox continues to face mounting pressure on market share from Google Chrome and Microsoft Edge, making standout features that attract and retain users increasingly urgent. Supporting AAA cloud gaming – combined with Firefox’s distinctive picture-in-picture mode, sidebar tools, and customizable themes – effectively caters to the multitasking needs of gamers who want to play, watch live streams, or look up guides all at once.
