Quite new to Firefox. Had the tiles feature before. Now I just get a completely blank page. I updated a program called Web Companion which changed my homepage for some reason. I think this was the cause. Now I can't get tiles back, or see any option in the settings to get it back. The part of the help page which says "How do I turn the New Tab page off" may have been useful for me to turn it ON, however the blue gear icon they suggest I click on which allows the option 'Enhanced/Classic/Blank' DOES NOT EXIST! I even tried to reinstall Firefox to restore to default settings. No good either. No idea what is going on.
