I had 2 personas - then added another one. Then decided to add some more, did a couple of searches and so many terrific ones. After adding more than a dozen, I decided to uninstall a few that, by now, were not as enjoyable as ones I later found. Boy, was I unpleasantly astonished to find all but the last 7 or 8 there. All the earlier ones had been overwritten, gone forever. Why doesn't FireFox warn you that you can't install more than 8?? Is there any way I can change this setting and have more? Thank you so much for taking the time to help me out. Cricket
