Well, as I said, Firefox 3.6.8 crashes when accessing Add-on Manager and Google Toolbar (v 7.1.20100723W) is enabled. This is on a 2010 white unibody macbook. I have a google toolbar, and all of a sudden, it keeps saying that it can't communicate with the toolbar. Now, I can't even uninstall it because whenever I go to the add on manager, it says there's an 'unresponsive script'. Could anyone help me? Thanks.
