Firefox uses up all CPU and heats up the laptop if a page contains one anigif
This is pretty much the same as https://support.mozilla.org/en-US/questions/801343 back in Firefox 3.x → 4 times. I do recall having the same problem then, and disabling hardware acceleration did fix it back then, but it no longer does.
I’m currently on 115.3 ESR, but I’ve observed this for a while in Quantum (I don’t recall seeing it on Gecko with HW accel disabled).

page contains one anigifWhat page???
The login page of my employer’s time tracking system… which I probably may not share publicly.
If I isolate just the .gif and put it on a dummy HTML page with nothing else, it still eats up 50%, i.e. one of two CPUs in its entirety, though, so I suspect I’m seeing a combination of Bugzilla 595671 or 702892 *and* something with JavaScript, possibly a bad interaction of both.
Good luck... Jones out.
