Hi Fred, No password addons. Just Firefox out of the box.

And just to emphasize, Firefox works fine saving the login info for other sites - just not the Zoom.us site. And my other browsers have no problem with the Zoom.us site. For me, this behavior isolates the problem to FIrefox.

Problem solved. It was definitely a problem with Firefox itself.

I was on version 66. I just now updated to 71. Visited Zoom.us, entered my login credentials, and got asked by Firefox if I wanted to save my login info.

If you update to Firefox 70 then the Lockwise Password Manager will have an option to add a new password. In Firefox 70 Lockwise is a builtin component that isn't available for Firefox 66 (there is a Lockwise extension for 68/69).

(EDIT: I hadn't seen your last reply yet that you updated to 71 Beta)

I am able to enter ZOOM.us for video only. Firefox blocks only audio.
