Thread: Firefox-bin Maxes CPU and Freezes in Natty

hello,

i've had problem last couple days that's getting worse--on opening firefox, application freezes after thirty seconds , if check 'top' or system monitor, firefox-bin more maxing out cpu usage.

interestingly, firefox-bin continues max out cpu after i've forced firefox quit (see attachment).

had accidentally upgraded ff5 week or ago, thought might problem. downgraded ff4--same problem.

i'm using chromium workaround most grateful advice.

else having problem?
