My problem is with the 'organise bookmarks' screen. When the screen opens all I have in the left column is the heading 'All Bookmarks' and nothing else, clicking on this heading does nothing. In the main screen area there are just 3 web addresses all have 'null' at the end. It's as though 'Organise Bookmarks' is not looking at the right file (sorry I'm not really into the workings of Firefox! Finally just to say the my bookmarks in general are working OK (all 368 of them) it;s just I can't organise them. Any help would be very much appreciated. == This happened == Every time Firefox opened == When I upgraded to 3.6 (I think!)
