When accessing sites at my work I get various "authentication required" dialogues, i.e. from the intranet proxy server. Firefox does remember the username/password but I have to click the dialogue all the time; sometimes multiple times per site. Is there a way to make Firefox do this all automatically?

Afaik there's no NTLM or other advanced protocols in place.


Do note that, accepting all HTTP authentication dialogs automatically can be risky, because then you don't know when you have sent your credentials and when you didn't.

Good news is that there is a plugin for that: AutoAuth.

AutoAuth automatically submits HTTP authentication dialogs when you’ve chosen to have the browser save your login information. (If you’ve already told the browser what your username and password are, and you’ve told it to remember that username and password, why not just have it automatically submit it instead of asking you each time?)

    Cool, I'll try. In any case I want to accept *.mycompany.com; I already type my login/password blindly in any dialogue as I have to do it so often. – Frank Meulenaar Feb 23 '11 at 13:24
  • The link doesn't work any more. I searched and found AutoAuth, but it doesn't work for proxy promts. – Lion Dec 3 '19 at 10:04
