Thank you for taking the time to report this bug and helping to make Ubuntu better. This one is going to be difficult to troubleshoot. Maybe you can answer the following questions?
* Which flash package do you have installed? * Which Java package do you have installed? * Which Firefox extensions do you have installed? * How many tabs and windows do you have open in firefox? * does starting firefox in safe-mode help? "firefox --safe-mode" from the command-line. This will greatly aid us in tracking down your problem. ** Changed in: firefox (Ubuntu) Status: New => Incomplete ** Changed in: firefox (Ubuntu) Assignee: (unassigned) => Rolf Leggewie (r0lf) -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to firefox in Ubuntu. https://bugs.launchpad.net/bugs/704628 Title: FF unusually become very slow Status in “firefox” package in Ubuntu: Incomplete Bug description: Binary package hint: firefox Recently i had a FF crash.
