There are several different user screens on my computer with each users programs. We all use Firefox on our Windows 7 desktop. However, for the last week, when I hit my Firefox icon, a small window flashes across the screen and is hidden. However, it shows the open window and the default site on the Task Bar, and I cannot browse, although Firefox still works on the other users' screens. What can I do to use it again and still save my Favorites/Bookmarks?

Start Firefox in Use Troubleshoot Mode in Firefox to check if one of the extensions is causing the problem (switch to the DEFAULT theme: Firefox (Tools) > Add-ons > Appearance/Themes).
