[Bug 227185] Re: firefox 3 beta 5 on ubuntu 8.04 loads the cPU for 100% for random length of time

[ramki]

I also see this Firefox 3.0 Beta 5 in Ubuntu 8.04. For me CPU is not
hitting 100% yet but its slowly increasing over a period of time.
Currently, after 45 mins of usage its about 20%.

Not sure if it helps, upon doing a `strace -p <firefox PID>`, something
is going in an infinite loop looks like. Here is the piece of the
output.
