We're sorry to hear that your Firefox seems to be crashing when you open it. Please perform the following steps to give us a crash report ID that helps us find out more about the cause of the crash.

1. On the keyboard, press [Windows] The image "Windows key" does not exist. + [R]. This should bring up a Run window that contains a text field.
2. In that text field, type %APPDATA% and press Enter. An explorer window should open.
3. From that explorer window, double-click on the Mozilla folder, then double-click on Firefox and then on Crash reports. Double-click on submitted.
4. Now, you should see a list of files that contain reports. Go to View > Arrange Icons by > Modified to get the most recent files at the top of the window.
5. Open the most recent 5 files with a text editor and copy the IDs.
6. Paste each ID with bp- into the reply window on the forums.

Thanks in advance!

Firefox immediately crashes with WebGL. I have tried everything in the forums and nothing has fixed it. Downloaded new drivers for graphics cards, profiles, etc.

Note: I had to disable WebGL to access your Troubleshooting page in Firefox help. Otherwise it crashed Firefox.

You can try to toggle the layers.d3d11.disable-warp pref to true on the about:config page.

You can try to disable hardware acceleration in Firefox.

• Tools > Options > Advanced > General > Browsing: "Use hardware acceleration when available"

You need to close and restart Firefox after toggling this setting.

I have tried toggeling layers.d3d11.disable-warp to true, and disabling hardware acceleration. Neither fixed the problem.

Any other ideas? I would love to continue to use Firefox as my browser.

Solved! Set layers.acceleration.force-enabled to true
