High X CPU issues are almost always due to bugs in client programs where
they make too many X requests (e.g. stuck in a loop). The fact that
updating firefox resolved it for you supports this hypothesis.
Presumably a patch in the newer firefox solved it.

Title:
Firefox causing 100% X CPU load [Lucid]
Status in “firefox” package in Ubuntu:
Triaged
Bug description:
Xorg shows 100% CPU utilization just after opening firefox. Sometimes I'm
able to browse some pages before it locks up.
Usually the situation can be resolved by logging in through ssh, killing Xorg
process and restarting the gdm service. Sometimes intesad a hard reset is
required.
