With Windows 10 autofill with Firefox never worked for me even though the appropriate options were checked. I recently upgraded to Windows 11 and it worked! So happy. But that was only for about 2 weeks. And then a couple of days ago it stopped working. (Maybe from a Firefox update??) It's really frustrating and tedious even with the passwords being filled automatically when I start the login process with the user name. Is there anything that can be done?
Received suggestion by Cor-el. Worked, and then didn't. I checked about:config again and the suggested change I made went back to the default. Too much a hassel so I'll try not to be annoyed and just keep Firefox open all day to avoid re-logins.
Sounds more like a Addon is blocked or removing the AutoFill options and or the Security software is removing this option.
