[RFC2617]" Reproducible: Always Steps to Reproduce: 1. setup a /protected url protected by HTTP basic auth 2. launch the script against it Actual Results: Dialog box open for credentials Expected Results: JS alert popup "FAILED" see attached html test case.
Is the test available live somewhere? Note that all this code was revamped to follow the spec you cite (which postdates Firefox 3.6) for Firefox 4, so it's worth testing what the behavior there is.
Test is available there : http://demo.moroblog.info/FF_RFC2617/ I have the same behavior under Firefox 4.0b6.
Indeed. Thanks for the testcase!

Jonas, can we just hand back an authprompt impl in this case that cancels the auth request from necko, perhaps?

I don't know off the top of my head how necko handles authentication prompts, but that does sound like a possible strategy. Would be even nicer if we can simply hand back null of course.
(In reply to Benjamin Jaton from comment #3) > Test is available there : > http://demo.moroblog.info/FF_RFC2617/ The test case is currently broken, as a 500 (Internal Server Error) HTTP status code is being returned by the server, which is obfuscating this issue. @Benjamin: could you take a look? Thanks! Bumped at this issue a few months ago and worked around using some sort of trick. Now revisiting in the light of Firefox 4+ changes (which, unfortunately, broke the existing workaround). The use case is an HTTP-based authentication application which, for logout, uses an XMLHttpRequest with invalid credentials which was supposed to clear existing credential cache. Due to this issue, the authentication prompt is always displayed (i.e., cannot be prevented through scripting), which is confusing for users - who will likely try to authenticate themselves again, instead of pressing "Cancel" to keep in the unprotected area.

Hi Helder, the test case should be fixed :)
