Firefox says WebGL2 is disabled or unavailable, but Chrome works fine.

Hi,

I made a Mozilla account to post on this forum as this has been a puzzling conundrum. I am using Chrome temporarily (oh no!)

A friend of mine made a tool that uses Godot engine on web, and it requires WebGL2. About a month ago, I never ran into any issues using Firefox and I was able to complete an entire project using this site that used WebGL2. 2 weeks ago, I logged into the website and was prompted with an error.

Error The following features required to run Godot projects on the Web are missing: WebGL2 - Check web browser configuration and hardware support

Firefox was not loading WebGL2. I opened https://get.webgl.org/webgl2/ and got another error.

Hmm. While your browser seems to support WebGL2, it is disabled or unavailable. If possible, please ensure that you are running the latest drivers for your video card.

At the time I was running an older version of my NVIDIA graphics because I had experienced instability on my graphics card with the latest version, so I went to go install the latest version of my drivers. (ver. 617.42)

I then go to try both websites again, my friends' site, and https://get.webgl.org/webgl2/ . Both give the same error.

So I'm not really sure why, but I can't use any WebGL2 stuff on my Firefox install after fully deleting everything and reinstalling, it only works on Chrome. Please let me know what I can do to troubleshoot this because I actively want to use Firefox as my main browser. I will do anything to get to the bottom of this. --- Driver: NVIDIA GeForce RTX 4070 Ti SUPER Driver Version: 32.0.16.1742 Driver Date: 9 30 2026 --- Thank you!
