I was using Firefox 11 browser and recently upgraded it to Firefox 13 (the day when it got released).All of a sudden after updating to FF 11, all my Add-ons stopped working. I really don’t know what to do now. What exactly the problem is? Is this new version not compatible with all those Add-ons or mozilla released Firefox 13 with out any add-ons ? Please let me know as I just cannot work without the add-ons i was using with earlier version. Please help me in any way.
