I'm not good using computers. For some reason, blank tabs started coming up in a fast stream and by the time I could stop them, quite a few were created. I tried to delete each tab and did up to 32 of them. I decided to shut down and reboot. When I clicked on Firefox again, I had no information to click on to try to resolve the issue; only the Firefox logo and the grey settings were on the page. I clicked on bookmarks to get my websites that I needed to use. I tried logging out again to no avail. When the Foxfire logo comes up, the top of the screen that contains the info I need, scrolls off the screen and I can't access it to solve the problem.
