[Bug 892901] [NEW] Firefox freezes periodically for no apparent reason

[Stephen Rees-Carter]

Public bug reported:

Firefox keeps randomly freezing periodically for no apparent reason.

It can happen as often as every few minutes, or as infrequent as every
couple of hours. It also freezes often when the computer is started
again from being suspended. It usually comes good after some time, but
it's quite frustrating and makes it hard to get stuff done.

The closest step I can suggest for reproducing it is to suspend your
computer with Firefox open. That often causes the freezes.
