Hi. I am not sure if this is related to this bug, but I was having the same symptom.
In my case, Firefox was showing something to the effect of "click here to install plugin" instead of the video, but the installation would respond "plugin already installed". When I was installing "ubuntu-restricted-extras" something went wrong, but it still was reported as successful. Uninstalling and reinstalling the restricted extras either with apt-get or "Add/remove" would not change anything. I had to go to Synaptic, remove completelly "flashplugin-nonfree", reinstall it from Firefox, and now it is fixed. -- [gutsy] flash plugin reported as installed when it actually failed https://bugs.launchpad.net/bugs/139138 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
