passwords are auto-filling, but not usernames
On more and more websites passwords are auto-filling, but not the usernames - those now have to be typed in by hand for every login to these sites. This has been happening for a few months now. My Firefox Preferences are set to auto-fill them, and the passwords are saved with the usernames in saved passwords. Are the websites doing this, or is it a problem with Firefox? I'm using Firefox 130.0.1, Mac OS Monterey 12.7.6, Macbook Pro 2021.
