Just to wade into this discussion, I've been noticing a really
significant slow down in FF 4.? on Ubuntu 11.04.  My symptoms are
broadly similar to Simon and Richard's. When I wake my computer from
sleep I can use FF for about 90 seconds and then it pretty much grinds
to a halt. It is unusably slow for something like 30 seconds and then
it comes back to responsiveness.

I haven't dug into it too much but it sounded similar to what you both
are experiencing. The slowdown got so bad that I've switched to
midori[1] for day-to-day use.
