More Information

Task Manager shows Firefox.exe *32 process running at between 40%-50% and the application (shown by the cuurent tab) swiches between 'not responding' and running. Even closing with Task Manager is slow to respond - appears to take 2 to 3 attempts.
When I relaunch FF it opens with a single blank tab, not the home pages defined in Options/General. (Closing this results in the FEBE add-on running, as per scheduled) Closing this and re-launching results in the correct Tabs being displayed and performance being normal. (Task Manager shows firefox.exe *32 as running between 40%-50% for a few seconds and then it drops to 0%).
