The issue started happening in version 120 after an upgrade from 119.0.1.
I tried creating a new profile, disabling all extensions and theme but the issue is always reproducible.
I do see the following errors in the console right before the freeze:
MESA: error: Failed to query drm device.
libEGL warning: egl: failed to create dri2 screen
The only workaround I found so far is to set webgl.disabled to true in about:config.
I do have the latest drivers for my OS.
The issue is 100% reproducible in this way:
- Start Firefox by clicking on the desktop icon
- Enter
about:supportin the address bar - Click on
Copy raw data to clipboard
Expected results: The data is copied to clipboard without any freeze or lag.
Actual results: Firefox freezes and a popup modal appears asking to Quit or Wait. Waiting does not do anything as the modal appears again. Quitting is the only way out of this.

The Bugbug bot thinks this bug should belong to the 'Core::Graphics: CanvasWebGL' component, and is moving the bug to that component. Please correct in case you think the bot is wrong.
I think I found what the issue is. It's AppArmor blocking Firefox access not sure why the Firefox profile /etc/apparmor.d/usr.bin.firefox is not giving firefox proper access
I disabled the profile temporarily using the following command
sudo apparmor_parser -R /etc/apparmor.d/usr.bin.firefox
