Firefox 5 on WinXP laptop. fully updated re microsoft. Updated FF twice yesterday from old version. Went from say 3.4 to say 3.6 (can.t remeber precise nos but were version 3) then went to FF5. Since then whenever I open FF5 a box opens (Firefox Update) that says its "checking the compatability of add-ons". It does this automatically. FF5 opens with 4 tabs open - my homepage + other 3 = add-ons eg foxtab + firefox update. A second page opens with a single tab open for another plugin. The browser works perfectly. Also says certain add-ons are not compatible eg google toolbar for FF5 yet on my PC (Win7) have had no similar problems

I am a Windows XP user and had firefox5 installed automatically by the auto-update system. From then on my problems started. I eventually found that the quickest, cleanest way to solve this problem was to save my bookmarks as a html file. Then FULLY uninstall firefox5 and delete the folders in C:\Program Files\Mozilla Firefox and C:\Documents and Settings\"username"\Application Data. I then did a clean, fresh installation with Firefox 5.0.1 (which is now available) and reloaded my bookmarks from the saved html file.
