Abnormal CPU usage on firefox

[psxlover 31]

Having Emby Web open in a firefox tab is making firefox constantly use 12-13% of the CPU (one hardware thread). It happens no matter what page I'm browsing (dasboard/home page/series...).

I noticed it while using version 3.1.5, but after updating to 3.2.5 it still seems to be an issue.
 

 
As soon as I close the Emby Web tab firefox cpu usage drops to 0-1%

I don't have the Mozilla ticket handy but it's due to a detect in Firefox with requestanimationframe.

Thanks for the quick reply and sorry for opening a new thread, seems like the search I did was only in the web client forum.

Confirmed still doing it in Firefox 51+

 

I was on 64bit FF also!!! If you do not install 64bit by obtaining @ more downloads link FF usually installs 32bit been seeing a lot of people thinking they are running 64 when it was 32 all along even through all past updates

 

 

Also confirmed that fix works fine I had to look it up last night
