Steps to reproduce:
https://alteredqualia.com/tmp/webgl-maxparams-test/
According to this website, Firefox doesn't provide detect GPU correctly and doesn't provide all extensions available.
This makes Firefox to work much slower compared to Chrome.
Tests show that Chrome renders pages about 1.5x faster using less resources.
Actual results:
Firefox 93.0:

The Bugbug bot thinks this bug should belong to the 'Core::JavaScript Engine' component, and is moving the bug to that component. Please revert this change in case you think the bot is wrong.

The severity field is not set for this bug.
:jgilbert, could you have a look please?
For more information, please visit auto_nag documentation.

95 is an ANGLE update ahead of 93, so it's expected that it gives similar capabilities as Chrome.
Firefox doesn't report the exact GPU string anymore, as of 91: bug 1715690
Are there any other specific concerns you have? We are aware of some amount of performance differences between Firefox and Chrome, and we're chipping away at that already.
Glad to know about work in this area.
I would expect Firefox to be as fast as Chrome :)
Thanks.

Do you have a specific testcase that's slower in Firefox than Chrome?

Chrome has 1.5 higher result than Firefox.
