In this vein, I can’t even register for GitHub on Firefox due to laggy animations. Works fine in Chrome. Did they even test it?

You aren't kidding. On Firefox 120 it ramps up a Xeon core to >50% and floors my GPU 3D at 100%.

I opened on Opera and CPU is negligible, GPU is steady at 15% (which still seems high for a throwaway web background).

for those playing along at home: https://github.com/signup?source=login

My CPU was at 27% (i3-4130) and 27 watts power use vs. 11w at idle. Added uBlock filter: github.com##div.signup-stars and CPU was back to 1%. Background stars animation is the culprit.

On a browser with like 5% uptake? I'd be willing to wager they didn't test it on Firefox. They probably didn't test it on Brave either.

I’m sure everyone is a 5% edge case somewhere

Poor Firefox users are 5% edge cases everywhere :(

I can't support this with data, but I expect the percent is a bit higher among potential GitHub users

I'm not sure. My total lack of data suggests that they are GitLab users.

For GitHub, Firefox usage will be way higher.

And besides “Microsoft <3 Open Source” right?

… Right?

huh? works just fine for me in Firefox

I'd be willing to wager the X Factor is graphics card configuration and a card optimized for high performance 3D rendering (including having the drivers installed properly to leverage those features).

There's a bit of a correlation between Firefox users and users who are mostly content that their hardware supports explicitly a 2D desktop GUI and is not optimized for anything fancier. But nowadays, the browser itself is a 3D application because the 3D compositing pipeline is also the high performance 2D compositing pipeline.

Dunno, I use FF on all my PCs with a variety of configurations and do not experience the GitHub slowdown referenced earlier.
