Using Samsung Galaxy S2 (android 4.4.4) and latest stable Firefox (it also happens with beta). When i am browsing any page and turn the screen off, Firefox constantly uses 30-50% CPU and keeps my device from deep sleep, which results in heavy battery drain and hot device after 20 minutes. Sometimes, Firefox keeps using same % of CPU in background even after I've switched to another app.

HI lolnade, Are you on wifi or on Data 2G/3G?

Also the Telementary data sent on the browsers can help improve the performance. There are also automated tests done to check performance of different platforms.

If you are interested in providing a website example this could help create a bug. With the websites, there are have these tools to test the performance of the profile as well: for android local host builds these test can be reproduced here: https://developer.mozilla.org/en-US/d.../Profiling_with_the_Built-in_Profiler#Profiling_Firefox_mobile

There is also DTrace that can help optimize development on javascript pages https://wiki.mozilla.org/Performance/Optimizing_JavaScript_with_DTrace#Ti...

We look forward to your reply!
