[Request] Hide save password popup

[teknowledgist]

Firefox has an option to store passwords. Most of the time I do not want to store my passwords in Firefox, but there are a (very) few sites where I would. While ideally, there would be a setting to "use stored passwords" and a separate setting to "ask to store passwords", there isn't. (Somewhere is a feature request for this, but I can't find it at the moment.)

Is there a CSS way to block/stop the "save your password" popup? That would allow me to store and use the few passwords that I want but never have the annoying popup appearing.

I used to use this:

panel[popupid="password"]
{
  display: none !important;
}

but it does not work any more.

Thanks!

Does #password-notification{ display: none } work?

It does not appear to work.

If this is still of interest: the following does work for me (Firefox 82.0) in userChrome.css:

#password-notification { 
   display: none !important;
}

In order for userChrome.css to still be evaluated, the following entry has to be set to true in "about:config": toolkit.legacyUserProfileCustomizations.stylesheets = true
