windows 7, and I open window, which then flashes across the screen and is then hidden (only on my screen--the other users are able to open Firefox). What can I do?
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 Diagnose Firefox issues using Troubleshoot Mode to check if one of the extensions is causing the problem (switch to the DEFAULT theme: Firefox (Tools) > Add-ons > Appearance/Themes).
- Don't make any changes on the Safe mode start window.
