@ Tom, your suggestion didn't help. In fact, if the global menu bar is switched on, than firefox in my case is not useable at all because it just stops whenewer i want to go from bookmarks to a desired webpage. It just stops not only firefox but all Unity on Ubuntu 12.xx (04/10).
So, i had to disable it earlier but it just helped only for a bit with bookmarks (i have about 6.000), Unity doesen't froze now but just like the others wrote, with time firefox is just slower and slower, and there is a point where i have to close it because it can load my cpu to a 70-80%, and i see that scrolling page is not smooth at all, it's just laggy, very laggy to a point where it just gives me mad, what is funny? I have Quad Core CPU named X4 955 running at 3GHz...I have also Windows Vista and on Vista i have never seen such behaviour, no matter how many tabs are opened (even with for an example: 50 tabs), no matter what i run, what i selected in firefox, which page im on (Youtube and moves from it even with 720p or 1080 running) or how many firefox instances are opened - it's just always smooth. Under ubuntu, not. No matter which version of Ubuntu or Firefox. I have checked it also on Lubuntu, Kubuntu, Xbuntu, Slackware - everything works...exept Ubuntu. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1064474 Title: Firefox high cpu usage To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/firefox/+bug/1064474/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
