More tests showed me that this is not when switching tab that the problem happens but when trying to use the History menu commands. I tried launching FX in safe mode, no tabs open except the main one with Google search page, and as I click on the history menu, FX starts to use 100% CPU for about 1 minute.
So I emptied my history and all works nice. I used firefox sync to retrieve all my history, prefs and passwords from home to this new PC. I never had this problem even on my EEEPC. here it's a Dell optiplex 360 with 4Go RAM and 2 cores CPU, I should not freeze if an EEEPC doesn't... Any perfs issue between ubuntu and FX ? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/845592 Title: Firefox 6.0.2 process rises to 100% of CPU use when switching tab To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/firefox/+bug/845592/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
