Firefox will not open windows that are linked on a site, for example reviewing a piece of work that has a link which opens it in a new window.
There are links on site that open in new windows and close after you are done. Like A review link/box. The window opens but it's a blank page and the url books just says "search bookmarks and history".
This happened
Every time Firefox opened
== I changed a theme/Just before I upgraded firefox

Do you have that problem when running in the Firefox SafeMode? http://support.mozilla.com/en-US/kb/Safe+Mode Don't select anything right now, just use "Continue in SafeMode."
If not, see this: http://support.mozilla.com/en-US/kb/troubleshooting+extensions+and+theme...
