I had a user name and password from when I started using Firefox. Went to log in and instead of letting me log in it required me to sign up with my email and a password. I was a contributing user and just had a question on Browser.
on which site did you try to log in?
There were so many options so not completely sure. Pretty sure it was Mozilla Log in and Mozilla jam also comes to mind.
I was looking for help as I wanted to install a second version of Firefox. I currently use 68.4.1 ESR, I have a program that will not work with this version. So I needed to install a second which was 52.0. ESR to work. I did find a you tube and was able to install the older version although it updated to 68.4.1 automatically. I uninstalled it and my Firefox would not work at all this morning but I was able to reinstall and all is good now. But still do not have the 52.0 ESR. My Firefox initial install was some time ago I think around the begining and my user name was jnlh. Is it all email address now? And any assistance on the 52.0 would be great.
