The moment so many users have been clamoring for has finally arrived. NVIDIA's GeForce NOW cloud gaming service is now officially available on Mozilla Firefox. The company confirmed the news alongside the Mozilla team, and it comes after months of collaboration to ensure the smoothest possible experience. Until now, gamers who wanted to enjoy this catalog of games on the web had to settle for Chromium-based browsers like Google Chrome, Microsoft Edge, or Opera GX. Firefox was left out, with all the drawbacks that entailed.
The wait hasn't been short, not by a long shot. In fact, we had to resort to tricks to fool the system into thinking we were using Chrome, but that caused technical glitches like the cursor disappearing mid-game. That's all in the past now. Windows users can now freely access play.geforcenow.com from the latest version of Firefox and start playing without further ado. However, it's essential to be clear about which versions and requirements are needed to take full advantage of this new feature.
Everything GeForce NOW has to offer in Firefox: resolution and speed
One of the most striking features is the performance offered by the service within Firefox. As NVIDIA explained, GeForce NOW Ultimate subscribers can enjoy 1440p and 120 FPS without leaving the browser tab. This is possible thanks to the servers powered by GeForce RTX 4080s that run the service, so a powerful graphics card isn't necessary in your local computer. If you prefer the free option, that's fine too, because you'll also have access to a basic server with 1080p and 60 FPS.
Compatibility has been confirmed with Firefox version 154, which has been available for just a few days. This version, by the way, not only brings GeForce NOW but also fixes 58 security vulnerabilities and introduces some performance and page translation improvements, as well as the ability to skip to another position in a video much faster. Cloud gaming support comes after Mozilla's browser had to meet a series of strict technical requirements, because game streaming demands a level of responsiveness that not everyone is willing to provide.
A library that syncs with your usual accounts
When it comes to gaming, the offerings are unchanged from NVIDIA's desktop client, which is great news. You can easily link your games from Steam, Epic Games Store, GOG, Xbox PC Game Pass, and Ubisoft Connect simply by logging into the service's website and accepting the link. In total, the available catalog exceeds 2.000 PC titles, although NVIDIA has gone further, stating that there are more than 5.000 overall. The number varies depending on the source, but what's clear is that you'll have plenty to choose from.
Among the games mentioned in the service's presentation are titles like Cyberpunk 2077, Halo: Combat Evolved, and Fortnite. However, availability will depend on your game libraries and what you've already purchased from each store. Firefox compatibility doesn't mean you'll have access to every game in the world, but it does provide entry to everything you already own in those accounts. In this sense, the integration doesn't limit the type of store, so you can distribute your library across several and access them all from the same GeForce Now session.
What gaming on Firefox entails: multitasking, Discord, and more
Playing cloud games through the Mozilla browser offers advantages beyond simply starting a game. It allows you to keep multiple tabs or windows open while playing ; in fact, you can leave the game running in one window and, in another, have a Discord call in Split View, consult a guide, or simply browse social media without interrupting the game. However, everything depends on your internet connection speed and how you optimize TCP/IP to reduce latency , which is the factor that most affects signal quality.
There are also extra customization options, which essentially encourage you to give your gaming window a special touch. Firefox has added the ability to create a window specifically designed for GeForce NOW, so it stands out from the other tabs you might have open for work or other purposes. If you used to get confused with the window manager, now you'll have it much easier to identify. And don't forget to enable automatic browser updates, because the service will require the latest version of Firefox for everything to run smoothly.
Firefox 154: browser requirements and new features
For everything to work correctly, you need to update your browser to its latest stable version, which is currently 154.0. This version arrived with 58 vulnerabilities fixed, according to Mozilla's security report, and with notable new features such as faster video navigation and automatic language detection for more reliable translations. Firefox 154 is the first version to include official support for GeForce NOW on Windows , and to activate it, simply open play.geforcenow.com.
Version 154 for Windows is the one that focuses on GeForce NOW compatibility, but it's not the only new feature Mozilla has prepared. The ESR 153.1.0 branch, also released this week, includes fixes related to the previous codebase and, of course, addresses those same vulnerabilities. Meanwhile, the Firefox versions for Linux, macOS, and Android have also received the update, although cloud gaming integration is not yet available on these systems, at least not in the same way as on Windows.
The registration process is as simple as ever: if you already have a GeForce NOW account, just log in with Firefox and your library will be linked instantly. If you don't yet have an account, you can create a new one directly from the service's portal. Mozilla and NVIDIA have confirmed that they will reveal more details about this collaboration during Gamescom, which begins on August 25, and it's quite likely they will expand the service's roadmap for browser integration.
Other new features in Firefox 154
That's not all that's new in the latest version of Firefox. The free VPN that arrived in Firefox 149 continues to expand its reach temporarily and is now available in a selection of 28 countries until the end of August, although it has been limited to the United States, Canada, the United Kingdom, France, and Germany. Firefox users on Android are also receiving this VPN through a gradual rollout, and iOS users may be next.
On the other hand, Mozilla wants the browser to stop relying on the language displayed on the website itself. Now the browser detects the actual language of the content and can therefore translate the text included in iframes. Tracking protection has also been affected, as pages that were on the cookie deletion exception list are no longer automatically excluded from tracking protection. And all of this comes with dozens of bug fixes, as I mentioned. Memory management was one of the main sources of problems, so that's where the focus has been.
Gamescom: the event where the story will be expanded
The Firefox community has been asking for something like this for years, and NVIDIA has finally responded. The collaboration between Mozilla and NVIDIA doesn't stop at GeForce Now support; all signs point to more developments to come. August 25th is circled on the calendar , because both companies have announced they will share more details about this partnership during Gamescom in Cologne. Improvements to the browser gaming experience or even more compatible games are likely to be announced, although nothing specific has been mentioned yet.
Until then, users who want to try it simply need to update Firefox, go to the GeForce Now website, log in, and choose their first game. There are no downloads or installations, and no need to wait for lengthy updates, as the game launches directly from the server. With a move like this, the future of cloud gaming within Firefox seems to be on the right track, although there's still room to explore more features and refine certain aspects of the interface.
With this integration, NVIDIA officially certifies Firefox as a GeForce NOW-compatible browser, a step that comes after several months of work by the Mozilla and NVIDIA teams. The result is that you no longer need to switch browsers to play cloud games, nor do you need to have another desktop client installed. Frankly, this is a huge relief for everyone who relies on Firefox for their daily gaming. Just update to version 154 and you're good to go. And if you have an Ultimate account, you'll enjoy the best possible web experience.
