I also am experiencing the same problem as well. Immediately after updating my flashplugin package (there was a security-update) from 11.2.202.233ubuntu0.11.04.3 (which worked) to 11.2.202.235ubuntu0.11.04.1 , flash videos in firefox no longer worked, firefox redirected me to the adobe website install flash [although it is installed].
firefox 12.0+build1-0ubuntu0.11.04.1 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/995022 Title: all flash contents are invisible in firefox To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/flashplugin-nonfree/+bug/995022/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
