Reproducible with both an old and new profile. Reproducible: Always Steps to Reproduce: 1) Launch FF (Latest build) 2) Load one tab pointing to http://forums.mozillazine.org/viewtopic.php?t=303519 3) Load a second tab pointing to http://bonsai.mozilla.org/cvsquery.cgi?branch=HEAD&branchtype=exact&date=week 4) Verify that both tabs have loaded completely and that the throbber is not animated/spinning. 5) Clear your cache 6) Reload/refresh the pages loaded in steps 2) and 3) 5) Load a third tab and type abouf:cache (yes, I typed abouF:cache) 6) You should notice that the throbber spins and never stops and the stop icon is enabled but you can't stop the "page load". The other two tabs inherit this behavior as well! Actual Results: The FF throbber spins forever, the stop button is enabled but doesn't do anything if clicked and the page loading progress indicator in the bottom right of the status bar is stuck and any previous tabs inherit this behaviour! Expected Results: Throbber doesn't spin and the page loading progress indicator in the bottom right of the status bar had completed as well as the stop button should not be enabled.
