So, I've done a bit of research today, and this seems to be a combination of flash, firefox, and the nvidia binary driver.
- All versions of flash 10 work properly - flash 11 with firefox 8 from the team PPA works properly flash 11.1.102.55 with ff 3.6.3 - works flash 11.1.102.55 with ff 3.6.6 - works flash 11.1.102.55 with ff 3.6.8 - works flash 11.1.102.55 with ff 3.6.9 - broken flash 11.1.102.55 with ff 3.6.11 - broken flash 11.1.102.55 with ff 3.6.21 - broken flash 11.1.102.55 with ff 3.6.24 - broken It seems something was introduced in firefox 3.6 that is causing the hang issues with flash 11. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/875538 Title: [Firefox 3.6.23] Impossible to open firefox because firefox-bin process is still running To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/firefox/+bug/875538/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
