why Firefox 18 behind proxy server is refusing all https connections?
I used to have Firefox 17 and everything worked ok but I just installed Firefox 18 in my Windows XP sp3 environment and I cannot connect to https sites through company proxy. Company proxy requires LM/NTLM authentication, proxy server is an IPCOP machine (squid proxy.) After updating to Firefox 18 for every site that uses an https connection the response is: The proxy server is refusing connections
Firefox is configured to use a proxy server that is refusing connections. Check the proxy settings to make sure that they are correct. Contact your network administrator to make sure the proxy server is working.
The log of squid shows lines with denied connection because of required authentication parameters (domain/username and password) 1357912572.640 1 (my ip address) TCP_DENIED/407 1586 CONNECT www.orange.ro:443 - NONE/- text/html As you can see no domain/username were filled in log. here is a line with permission granted from another browser 1357920874.657 1348 (my ip address) TCP_MISS/200 2549 CONNECT www.orange.ro:443 (mydomain\myusername) DIRECT/109.166.184.137 - I modified sensitive data

by Noah_SUMOI'm seeing a lot of proxy issues being reported by Firefox 18 users. So you're not the only one with this problem.
For the time being, I would advise you to go back to Firefox 17.0.1 until Mozilla fixes this bug.

This is a bug with how Firefox 18 handles some proxies. It will be fixed in Firefox 18.0.1, which should be out next week hopefully.

We, too, are currently seeing this issue. It can easily be reproduced and is temporarily fixed by rolling back to FF17.0.1. If I can be of any help fixing this issue, please let me know.

I have the same problem after updating from Firefox 19.0.2 to 20 in Windows 7. Our internal reporting portal uses Windows Authentication, and with 19.0.2 everything worked fine, but after update connections from Firefox are refused. Both Chrome and IE work fine.
