After installing flash plugin firefox needs to be restarted but isn't

[seanh]

Binary package hint: firefox-3.0

Using hardy beta. In firefox, visit a page that has a flash video embedded, e.g. a youtube video. A bar at the top of the browser appears saying the page needs plugins. Click on install plugin, go through the install process, great. You find yourself back at the web page in firefox, but the flash plugin is not yet working. Any embedded videos will just be replaced by 'Click to install plugin', even though you just installed it.

Restart firefox and visit the same page and the plugin works.

Quite confusing.
