Nvidia has finally added another major browser to its cloud gaming service, closing a gap that Firefox users have complained about for years.
The update, developed in partnership with Mozilla, gives another large group of PC users a way to stream games without needing to switch browsers or install a separate app.
Nvidia GeForce Now Gets Firefox Support
Nvidia and Mozilla jointly announced that Firefox is now officially supported on GeForce Now for Windows, letting users stream more than 2,000 PC games directly through the browser.
Ajit Varma, Head of Firefox at Mozilla, called the partnership a "milestone moment," describing it as one of the world's leading cloud gaming services now running on a browser built for privacy, control, and flexibility.
The two companies said the update followed months of collaboration and engineering to bring Firefox up to the same standard already offered on other supported browsers. GeForce Now Ultimate subscribers can now stream at resolutions up to 1440p and frame rates reaching 120 frames per second, matching the experience already available on Chrome, Edge, and Opera GX.
The update is live now for Firefox users running version 154 or later on Windows, though support currently does not extend to macOS or Linux.
Why Did It Take 5 Years After Chrome?
Firefox joins Chrome, Edge, Safari, and Opera GX as an officially supported browser, but it stands apart from all of them in one key way. According to 9to5Google, Chrome, Edge, and Opera GX are all built on the Chromium engine, meaning Nvidia only had to build support once, and it largely carried over across each of those browsers.
Firefox, on the other hand, runs on Mozilla's own Gecko engine, which is not controlled by either Google or Apple, requiring Nvidia to build and test compatibility from scratch rather than relying on shared underlying code.
That distinction is likely a major reason the rollout took as long as it did. Before this update, Firefox users hoping to use GeForce Now had to rely on workarounds like spoofing their browser's user agent to trick the service into thinking it was running on Chrome, a method that reportedly worked inconsistently and often came with its own technical issues.
Nvidia has not detailed the specific engineering hurdles it worked through with Mozilla, though both companies described the process as a genuine technical undertaking rather than a simple toggle switch.
Here's How to Launch GeForce Now
Getting started only takes a few steps. Firefox users first need to download or update to the latest version of the browser, since GeForce Now specifically requires version 154 or newer to work properly. From there, users simply need to visit GeForce Now's official streaming website at play.geforcenow.com and sign in using their existing GeForce Now account credentials.
Once signed in, the full library becomes accessible directly in the browser, covering games tied to platforms like Steam, Epic Games Store, GOG, Xbox's PC Game Pass, and Ubisoft Connect, depending on what a user already owns or has access to.
Nvidia has also confirmed that additional details about its partnership with Mozilla are expected during Gamescom, which comes next week, Tuesday, August 25, suggesting more updates to the collaboration could still be on the way.
