Description

5 years ago
User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:12.0) Gecko/20100101 Firefox/12.0
Build ID: 20120420145725

Steps to reproduce:

I opened my recent html5 development page in Firefox 12 / Windows 7 64bit Home. It's a project that heavily uses jQuery and animations and is already optimized for smooth animation (for example adding z-transform: 0 for enabling hardware acceleration on backgrounds). I tried with and without Firefox's hardware acceleration. Same result.


Actual results:

The page is not animated smoothly at all. It's very stuttering. It works fine in Firefox 12/OSX 10.6.8, Chrome Win7, Safari OSX, IE9 on the same computer.


Expected results:

Firefox should animate the layers with smooth 60 fps, synced to the screen.

Hello Jurek,

I just found this old bug report you opened in 2012.
since there was many update on html5, jQuery and Firefox, can you confirm that this is still an valid problem?
if yes, please give us a example to test on.
