AutoAuth
Note: watch the AutoAuth section of my blog for information on updates to this extension.
AutoAuth is an extension for Mozilla-based Web browsers that 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?)
If you don't have a username and password saved for a subdomain (e.g., foo.bar.com), AutoAuth will give you a list of suggestions for that domain, based on other saved usernames and passwords for similar subdomains (e.g., bar.com or *.bar.com). Just choose which username to use from the list, and hit the Autofill button:
AutoAuth is compatible with Firefox 1.5 - 3.b4 and Flock. If you're having trouble using the extension, you can either e-mail me at cfinke@gmail.com or leave a comment below.

Hi! :)
I couldn't make it work, see discussion here: https://addons.mozilla.org/en-US/firefox/addon/4949
Thanks. :)

When going to a page that requires authentication and your password is bad, AuthAuth continually tries to authenticate to that page. It should just popup the authentication dialog so that the user can fix the password and resubmit. As it is, I don't see any way for a user to update their password.
PS: To stop the flashing, close the tab.
I posted this at the addons.mozilla.org site as well.
Also I'm using Firefox 2.0.0.4.

Nice concept.
I tried it for a site that is annoying me today and no joy. Apparently it doesn't fill forms, only HTTP Auth requests? Not sure what that means exactly, but didn't work for me.
Would be great if it did form filling and auto-submission too, as many times use for access control. Then it would be REALLY cool...

Can you add a feature to detect when it gets stuck in a bad password loop? Thanks

Yeah, password change it flashing. How can I change the saved password?

Options tab is grayed out and I cannot use this add-on at all, even after two installation attempts.
Why not at least offer a context menu item to enter the un/pw for any given site desired?

Please work in Mozilla Thunderbird.
Because the reason is because there is RSS feeding in a basic certification area.

I don't understand how it's work (perhaps it doesn't work :)... Can you make a demo?

Hi, when i going to a page that using multiple accounts for authentication, i cant select between saved accounts :(

Would you be so kind to make the xpi installable in Thunderbird as well ?
This would fill in my proxy credentials whenever I receive a mail with www content.
Thanks a lot for this so nice extension.
Pierre.

Thank you, works fine and is very useful for me

This is a great extension and saved me 15-30 minutes a day entering in authentication information where I work. We do a lot of web work on many different environments and domains and it is so wonderful not having to re-type account information over and over again for new projects.
You rock!

Can you change it to be compatible with 3.0b5pre. I use nightlies and its a pain to keep editing the xpi everytime there is a version bump.
Thanks,
