For the last month the amount of letters/numbers/symbols in my address bar has slowly become less. It only happens when I have more than 1 tab &/or window open. It is now at the point where I'll have no more than a dozen characters in the address bar down to absolutely nothing being displayed there. I had HP do a wipe of my HDD & reinstall of the entire MS OS a month ago. I noticed the issue a few days after that but it was also after the first of 2 FF updates. Sometimes it has bugs but usually the next update fixes it completely; but not this time. I'm not sure if it Is a FF issue. I have checked all thru here and even scrubbed thru MS Win10 support pages and found nothing anywhere similar. Attached is a current screenshot. As you can see, there are only 4 characters in this header while 2 others have None and one has 11 +, 4 numbers and 6 random letters. This has me totally baffled.
