Since upgrading to FF7 (and 7.0.1) every time I use the "open all in tabs" command from the folder of bookmarks in the bookmarks toolbar, the whole thing freezes and never finished loading any of the pages. I also can't open another window and get anything to load there. I'm tried starting up in safe mode and still have the issue. I reinstalled FF6 right over FF7 and it was back to normal with no problems. No crash reports since it doesn't get that far. I have to close all windows and restart FF, then it works again until I try open all in tabs.
