Have problems with flash sites, after following the complete uninstall and delete instructions for flash, re-starting computer and re-installing, problems were still there, then tried to uninstall realplayer plugin, and noticed add-ons didn't open. It Does open in safe mode though, managed to uninstall rp plugin, but problems still exist. Re-installed firefox, didn't help either.
