I have the same problem on Firefox 8 too. It occurs only on one of my computers and only occasionally. Rebooting usually fixes the problem. The problem was more persistent on a live system, so it may happen because of low resources (I speaking of Intel Celeron E1400 @ 2.00GHz × 2 with 1GB RAM and GeForce 8600 GT/PCI/SSE2 or Intel 82945G/GZ).
The same bug is reported to occur in Firefox 8, 9 and 10 as well and on a different machine. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/879240 Title: Firefox hangs when trying to use any dropdown or right-click menu To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/firefox/+bug/879240/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
