I've been using Firefox as my primary browser. Up until this evening, when I logged in, I'd click on name and my user name would appear. Same with my password, which I'd long since forgotten, since I never had to type it in myself. Tonight, the login name and password boxes will not let me type in anything.
So, I moved over to Chrome, where I could enter my login name, and then was able to get a new password. Worked fine in Chrome after that.
Then I thought I'd give Microsoft Edge a go. Login worked fine. No problems.
While I was playing with browsers, I tried a long unused download of the Tor browser. Again, login worked fine.
So, back to Firefox, where the same problem was encountered. I still cannot select the user name box to enter anything. I can browse the forums, just cannot log in to the site using Firefox.
Any thoughts other than "use Chrome, Edge, or Tor from now on." I do like Firefox, mainly since I've got better ways to spend my time than setting up and learning a new browser.
