I think I am seeing a similar bug, and I may have a workaround. The CPU% goes up to 51.1 shortly after starting Firefox and stays there, regardless of number of open windows/tabs, Flash, no Flash, etc. sites.
After a while, the Firefox windows eventually fade to dark, as if "thinking," but never come back and I have to kill. I'm in Ubuntu Intrepid 2.6.27-16-generic, Firefox version info: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9.1.2) Gecko/20090729 Firefox/3.5.2 Searching online, I found the suggestion that there was a problem with the default Firefox theme in Ubuntu. Sounded weird, but I don't develop this stuff, so I downloaded some new 3.5 themes. After installing *any* of them, my CPU% has gone down to 16% or lower, and does seem to change depending on number of tabs open, complexity of pages, etc. You might want to try this. I'm currently using a theme called "Charamel" with no problems so far (1 day). -- Firefox use a lot of processor doing nothing https://bugs.launchpad.net/bugs/449664 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
