I started getting blacked out rectangular areas while scanning down any given web page. If I hit recycle, the box may temporarily disappear or move to another location. And if that's not enough, I'm also getting frequent crashes. I reinstalled a fresh copy from "Play" and only added "LastPass". And it to did not work consistently. I'm on a Samsung Galaxy 12.2 Note Pro running 4.4.2. Finally, I just noticed that the progress line, below the URL line stops about 3/4 of the way across I've been using Firefox for years on all my platforms with great satisfaction. Suddenly, BANG! I'm not a novice. Any suggestions? I also have a Samsung 10.1 which my spouse uses. While you're thinking, I'll check her's out. Thank you Dick Proulx Luckyduck@metrocast.net 207.324.5704 I'll snap an image of the next black out and send you an attachment.
