Do you mean to login to a web server?

In such a case you can use http(s)://username@example.com to force Firefox to ask for a password.

thank you -- thats a nice "trick" to know.

BUT alas not the solution :-(

Back story --- if you (at least for me) open a few FF sessions and copy the same URL (in this case your shortcut) each browser will pause until one logs in, and then the rest one by one start to login as well but each with dialog boxes.

I'm actually doing some load work and I need FF to start multiple sessions via LoadRunner yet be prompted with the stock "windows" authentication prompt....

so far IE has a setting that requests a manual login vs using SSO

thank you again
