I had the same problem on AMD64. I posted this fix that worked for me over here https://bugs.launchpad.net/ubuntu/+source/nspluginwrapper/+bug/152583
1) Uninstall flashplugin-nonfree if installed through synaptic. 2) Get a list of any Flash remains with nspluginwrapper -l 3) For me this showed a combination of 0.91.94 and 0.91.95 versions. I manually deleted every file listed. 4) Run nspluginwrapper -l again and confirm no files listed. 5) Then I installed flashplugin-nonfree again through synaptic. -- flash hangs firefox on gusty 64 https://bugs.launchpad.net/bugs/151805 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
