Edit- I feel stupid, once I ran it in sudo again and shut down correctly, all is well.
I'm running ubuntu 8.1 x64, but I had this problem in 7.1 x32 also. In 7.1 I just upgraded to 8.1, so never got around to fixing it.
A few minutes ago I was playing around, and used sudo to start up firefox. Wasn't able to do what I set out to do, but that's a different issue. When I was done I navigated to the terminal window and used ctrl + c to close firefox. On my next start of firefox it opened to a blank page instead of my homepage and my bookmark bar(which I keep to the right of tools, help, etc.) will not show up. I tried restarting firefox and ubuntu without change. Not a life-threatening issue, but its frustrating to me for my homepage (google) and my bookmarks to not show up.
