Public bug reported:
When a tab with the Facebook home page is active in Firefox, Firefox's
CPU usage shoots through the roof. It had been very bad for a while, but
recently it has got worse, now sticking at almost a constant 100% on one
core (of a 1.5GHz Core2Duo), as opposed to around 5-20% when the page is
backgrounded or closed.
I cannot reproduce this problem in Opera. I have also read reports on
forums that say this problem does not occur in Chrome.
