Auto Fill does not work with htaccess authentication

Hi,

I’ve using bitwarden somme weeks ago, and auto fill does work well in general authentication page, using the option Host.

But i the last days, i tried auth with htaccess, and dont auto fill, i can copy password but i can auto fill, and in LastPass it does well.

There are any way to auto fill ? Or isnt possible ?

Im using:
Windows 10
Firefox 88.0.1

Regards
