Broken in latest version of firefox on both windows and linux

Currently broken in FF , PLEASE FIX ASAP!!! I spent the entire morning freaking out because I didn't have my passwords saved in another location. In FF a work around is to go to your add ons manager and disable/enable the application you'll then get the older looking log in prompt which works. FIX IT NOW please!

This is the THE MOST FRUSTRATING THING I have ever encountered. I can find NO WAY to get to a human being to help me. I am stuck on page in FireFox about ADD Ons, but can't seem to get anywhere.

UPDATE Sep 22, 2020.
Still not working. Updated Firefox, uninstalled & reinstalled Lastpass. No Luck.
I used to like and use this Firefox plug in but since past week it is not working on my Windows 10 desktop. I can't login at all. All I get is a message "an unknown error occurred"
Looking at alternatives to Lastpass.

I installed, I guess, and the next screen says almost done, click LastPass browser button above to login. But there is no browser to click.

Had trouble with the Auto Fill feature sometimes not working, overall a good extension now they decide to limit features for long time free users such as myself out of no where. No thanks, Bye. Bitwarden here I come!
