Expected results: Manageable interactivity, even if animation stays slow. Chrome is usable, Safari is smooth.

(In reply to Gerald Squelart [:gerald] from comment #0) > slows down whole browser, even with E10S. Everything's fine for me, 38.0a1 (2015-02-02) Win 7. Please check if the issue occurs using Firefox in safe mode (with your addons disabled): http://support.mozilla.com/kb/Safe+Mode And on a new, empty profile: http://support.mozilla.org/en-US/kb/Managing-profiles#w_starting-the-profile-manager

Same issue with the following combinations on an 2011 27' iMac with a 3.4 GHz Intel Core i7, 16 GB: - FF35.0.1, Mac OS 10.10.2, existing profile and add-ons. - FF35.0.1, Mac OS 10.10.2, safe mode. - FF35.0.1, Mac OS 10.10.2, new profile. - FF38.0a1 w/ e10s, Mac OS 10.10.2, safe mode. - FF38.0a1 w/ e10s, Mac OS 10.10.2, with new profile. - FF35, Win 7-32 / VMWare / Mac OS, fresh install, no add-ons. - FF38.0a1 w/ e10s, Win 7-32 / VMWare / Mac OS, fresh install, no add-ons. In Windows, Chrome has a similar speed as in Mac OS, IE is smooth and responsive. Just to be clear (in case we're looking at different things), when going to p5js.org, I see an animation of wave-like ribbons, moving from right to left and shifting up and down slowly towards the mouse pointer; Moving the mouse pointer left/right seems to have an effect on the shape of the waves. There are also light bubbles falling all over the page. By "slows down" I mean that the animation is very shaky, the waves are redrawn every second to half-second, and trying to scroll is very slow to respond, maybe 2-3 second latency. Switching to another tab in FF35 (hiding the animation), there was still some sluggishness. FF38 is better when switching, but same sluggishness when both tabs (anim + another simple page) are visible in separate windows. Please let me know if you'd like me to run more specific tests.

Component: Untriaged → Graphics
Product: Firefox → Core
Version: Firefox 38 → 38 Branch
Maybe a good animation jank test case, haven't looked closely yet though. Chrome performs very poorly on my machine.

Confirming the issue on 39 , linux 3.19, macbook pro retina 13. Heres a profiling session of the issue: https://www.dropbox.com/s/38xq8sc3o2dicm1/m8EnuGa7.exe?dl=0
Not sure why the gecko profiler appended .exe, but it most definitely is json...
