How much memory do you have?     If you have enough tabs/windows in
firefox and/or have things that use flash things can easily page on a
2gb machine...and that will cause the machine to respond poorly for a
while depending on how fast your paging device is.

ps axuww | grep -i firefox will show you the process and how much ram it has.

running "vmstat 1" will tell you how much the box is paging...so if
you start the vmstat first and then wait and check its output after
the event happens you may be able to tell if it is paging.
