I have the same problem, but on an old dual-core desktop machine, firefox takes up to 105% CPU (or more) and often freezes the whole machine.
A typical example is when sufing the: http://izismile.com/ web site and open a few tabs with some of its pages. There's always a moment where you open a page like: http://izismile.com/2016/06/03/page,2,daily_gifdump_30_gifs.html and the whole firefox / computer freezes. Interestingly, just opening a single tab with the page: http://izismile.com/2016/06/03/page,2,daily_gifdump_30_gifs.html alone does not seem to cause any problem. Also, using about:config and all its options to clean up memory (GC/CC/Minimize) does not help... So I assume there is a memory leak somewhere that reveals itself under high usage. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/916591 Title: The browser causes 20-40% CPU load when displaying an animated gif To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/firefox/+bug/916591/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
