Ever since updating to 3.6, I have had an annoying couple of problems. I cannot seem to get rid of another application's page that always pops up before my chosen Sign-on site (msn.com). No matter what I do including uninstalling and reinstalling Firefox, it is always there (so, by the way, are my bookmarks, making me think uninstall in not all-inclusive). Second problem is that I click on the desktop icon to sign in, and it flashes but does not open. When I click again it says Firefox is already running but not responding, and I have to reboot.
