I'm slightly irked at the Ubuntu Firefox maintainers right now. Back near the start of May, I reported a bug that prevents people from installing Flash using the Firefox Plugin Finder.
The Firefox Plugin Finder is the little wizzard that pops up and walks you through the Flash install if you don't have the plugin. The alternative is to do things the nerdy way and run "sudo apt-get install flashplugin-nonfree". Hardly as obvious or intuitive.
I have reported both the cause and an easy workaround. Maybe I don't understand what's going on, but it looks like they are ignoring the solution I posted.

Certainly currently in my test system strace reveals that whatever the problem is, it's probably not a missing plugins directory somewhere and probably not a permissions problem.
If a missing plugin directory isn't the problem, why does creating one fix it? Can't a bash script create it the first time Firefox is run? It would be rather hackish, but it would provide a termporary solution until the source code or whatever is fixed.
The whole thing is rather frustrating.
