I can confirm this bug. It seems to be the worst on YouTube, but can be triggered by any Flash content when clicking the Back button, closing the tab, or otherwise leaving the page with Flash content. This is very annoying.
Confirmed on Dapper 6.06 with the latest Mozilla build of Firefox (2.0.0.4) and Flash plugin and on Feisty with the latest Ubuntu build of Firefox (2.0.0.4) and the latest Flash plugin -- Firefox hangs when closing a page with flash running https://bugs.launchpad.net/bugs/98688 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
