Most users are not seeing such problems.  Are you also using gnome
flashback (Phil said flashblack but I presume he meant flashback)?
Could it be pages containing flash that are causing the problems?
That is a question for the OP also.  In Firefox install flashblock
addin which prevents it running flash until you allow it, and see if
that makes a difference.

It may be that 2GB of RAM is a bit low.  Run System Monitor (or top or
htop if you prefer command line) and see what the usage is when it is
going wrong.  Watch for swap being used significantly.
