Thank you for classifying this bug, I wasn't sure whether to classify it as Firefox, Matchbox ( I've never seen it on another WM like Fluxbox or Metacity ) or Xorg.
Further information: This only happens in the 'Addon' window when the 'Get Addons' tab is selected. The other tabs do not cause the high CPU usage. It also happens during the 'Install Addon' dialog which I'm sure many Firefox users would have noticed which is why I thought it wouldn't be a Firefox issue. I will test with another WM and see if this bug is Matchbox specific. -- Firefox Addons window pegs Xorg CPU usage https://bugs.launchpad.net/bugs/331219 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
