Something similar happens to me, I am watching a video at www.youtube.com and before the video ends, I click to see another or I go back to the previous page and then Firefox freezes. It seems it starts loading the next page and almost at the end it gets "stuck". If I wait for the video to finish, it works fine.
I am using Feisty Fawn herd 5, x386 (32bit), with an AMD64 system, Adobe Flash Player 9. I do not have any reports in /var/crash/ after or before the crash. I am new to Ubuntu so could you tell me how I see the version of the packages? -- Desktop freeze when right clicking on a flash with Firefox https://launchpad.net/bugs/87440 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
