Sorry, that doesn't help much. It looks as if you are now using an older version of Firefox (12.0) on the laptop than you were when you reported this bug (firefox 15.0.1+build1-0ubuntu0.12.04.1).
Compiz is indeed the name of the OpenGL-using compositor being used behind Unity3D. It has had some notable fixes recently if you want to try reinstalling Ubuntu on the laptop and updating compiz and unity to the latest versions, and updating Firefox to version 18. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1050730 Title: Firefox on Unity3D unusabley slow To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/firefox/+bug/1050730/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
