Charlie, bug 338785 is generic, I don't know it is also related to this issue. In both bug 338785 and mozilla bug 427028 (upstream bug) the question related to firefox plugin isn't ever sayd so I shouldn't mark this bug as duplicate of 338785.
However I confirm the issue on 10.04 and firefox 3.6.13 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/259574 Title: firefox flash install requires restart -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
