Plugin “management” in Firefox is a joke. Total engineers solution, no elegant at all. Chrome does a much better job.
[1] The ones you use are never ready when there's an update.
[2] They always need updating, a time consuming process involving multiple clicks.
[3] The damn thing has to restart afterwards.
I probably notice this more because I only launch Firefox once every week or two, but when I do I can guarantee one of the first things I'll be doing is restarting.
True, one would hope at least some of the information from the plugin engine created for Flash would be reusable for the extensions. Would help mitigate issues, although I am not quite imagining a great interface for the actual suser management of plugins.
