Updated my software today and now my Firefox closes on webpages I never had problems with before- OS 10.6.5 Firefox 3.6.13 operating on iMac 10,1

Question

Message;
Firefox is having trouble recovering your windows and tabs. This is usually caused by a recently opened web page.
- try removing one or more tabs that you think may be causing the problem
- startin an entirely new browsing session
Neither works keeps closing with message reappearing

Answer 1

With Safari launched go to: Safari>Safari Preferences>Extensions and if you have any installed switch them all 'off' using the switch at the top right of the window. Also whilst in preferences make sure you don;t have Glims listed in the tabs at the top of the window. If you do, there is an uninstaller available here:

Once you've turned off the Extensions quit Safari, relaunch and test.
If you do have Glims installed Safari needs to be quit when you run the uninstaller.
If Safari works with the Extensions set to off, switch them back on but disable each one individually (in Safari Prefs>Extensions) and then enable them one at a time and test.
On other thing - possibly important - have you installed Trusteer's Rapport, which is often pushed at you by banks as being 'added security' software. If so, it is a possible cause of the problme as it seems to wreak havoc for some users with otherwise healthy Macs.
