Upgrading firefox to 3.6.12 causes the Xorg process to run @ 100% CPU time.

  • OS is: Red Hat Enterprise Linux Client release 5.4 (Tikanga)
  • Previous version of firefox: 3.01
  • New version of firefox: 3.6.12
  • Other changes: upgraded from adobe website

Note that the previous version of firefox is still installed at /usr/bin - I have to start the new version of firefox using: ~/bin/firefox/firefox -no-remote.

As mentioned, when using firefox 3.6.12 with all add-ons disabled, something triggers the Xorg process to run @ 100% (as viewed by top) - memory consumption remains normal. For example, opening triggers this problem. Memory usage remains normal during this time. Opening up the same set of pages (as the session information is stored by my profile) using firefox 3.0.1 does not cause any problems.

I've had no end of problems with 3.6.x versions of Firefox and finally switched to Chrome. – tcrosley Nov 17 '10 at 0:46

You can try renaming (or removing) ~/.mozilla to see if it solves the problem. You can also un-install 3.6.12 and install 3.0.1 manually.
