I've been told there's no setting to change this behaviour and I'd like to file this feature request to make a setting for this popup window not to show up. Reproducible: Always Steps to Reproduce: 1. Sorry I don't have an open test web-server I can provide you with the login for, but try accessing an URL like: http://seangrisham:email@example.com Actual Results: A popup window You are about to login to the site "www.test-site.com" with the username "seangrisham" comes up. Expected Results: I'd like to have a setting in preferences to get rid of the Firefox popup window.
You can effectively disable this by using about:config to set network.http.phishy-userpass-length to a number larger than any user name you use to login. See bug 243572 comment 3 and bug 276018 comment 2. *** This bug has been marked as a duplicate of 243572 ***
