I'm using Firefox on OSX Lion. I also use Windows 7 on a vmware Virtual Machine. I have the proxy set correctly, safari can use the proxy. I don't get asked to authenticate but firefox tells me it can't establish a connection to the website. It works correctly on Windows 7

Same problem here. We have several people in our office using Macs and those with Lion cannot authenticate to the proxy using Firefox - it doesn't ask for credentials and the proxy returns a "failed to authenticate" error page.

Safari and Chrome work as expected. I also have a Windows 7 VM and FireFox works fine in that.

It seems to be only Firefox on Lion. I upgrade to Lion around Firefox 5 and am now up to FF 9.0.1. Problem still persists.

Solved it!

Browse to about:config. Filter on network.neg, and double-click network.negotiate-auth.allow-proxies to set it to false.

Firefox will then correctly prompt for proxy authentication.

Yes, it prompts but never actually authenticates. It will keep coming back to the authentication screen, irrespective of if you use the correct authentication details or not

Yes, it prompts for authentication but it never actually authenticates. It keeps cprompting for authentication, even if you are using the right username/password.
