When I woke up this morning and opened Firefox on my Android device, the homescreen was fine, but when I went to a web page all that was displayed was a small rectangular box about the size of two postage stamps with a portion of the webpage inside it. The rest of the web page was blank. The problem persisted anywhere I tried to go other than the home screen. I tried uninstalling, reinstalling, and every iteration in between. I can't figure out what the heck is going on, other than it could possibly be one of my extensions. On my Firefox for Android, I have ad blocker for Android, ublock origin, and self destroying cookies. However, when I uninstalled and reinstalled, I would think that would solve the problem because those extensions would no longer be there. However uninstalling and reinstalling did not fix the problem. For a brief moment while I was playing with it, it returned to normal and I thought the problem was fixed. However within 3 minutes the screen disappeared back into that little rectangular box. Has anybody seen or heard of this, and knows what the heck is going on?? Thanks so much.
