> Firefox is, on-average, 25% quicker with page loads than it was last year – and it was pretty fast then, too Is the copy I saw on update. Suggests incremental wins over the year rather than all in this release.

That's probably a good note though. If you're a FF user these gains probably won't be noticed because your window shifts to keep up (just like it is hard to see improvements in yourself because day to day gains might be small but add up over time). But if you aren't a FF user, this is quite the speedup and might be enticing enough to get you to try it again. Because there's still a general belief that FF is slow.

Anecdote: Firefox (124) has become unusable for me on Arch Linux. Highly resource intensive applications (particularly including video streaming, even worse with camera / webrtc) consume way more CPU resources to the point of my laptop lagging out. I don't remember the exact versions, but I upgraded to 124 earlier this month. Brave works great for video streaming, but breaks applications I use. Firefox development (125) also breaks some applications I use, and has the same performance issues as regular firefox. The fan on my laptop has been broken for most of this year (replaced due to first fan making noise, but havent had time to figure out why the replacement stopped working). I have been running with all high performance CPU features disabled in the BIOS for years with the purpose of not using the fan anyways, and it has been working great with 1 or 2 intensive applications max running in firefox (and as much other low intensity stuff that basically doesn't consume much resource such as another browser - chromium, vscode, my development environment including a vm). I don't currently really have any conclusive idea about what's going on. I will have to start using my desktop, fixing issues with my laptop, and do some more testing out of my workloads. Overall I'm just getting the feeling that something is horribly wrong with Firefox.

  Sounds like a hardware decoding issue to me

  If you encounter it again, consider creating a performance snapshot with profiler and submitting a bug to the FF tracker: https://bugzilla.mozilla.org https://bugzilla.mozilla.org
