I have a weird issue.I have a remote proxy server,with installed squid3.When access to proxy from Linux the server works perfectly,but from windows i get always the same message :

the proxy server is refusing connections

Linux and windows have same IP and same version of Firefox who give me that message. On windows I have check firewall settings and it seems OK.

thank you.

Make sure the port that you have set is correct. Squid should be listening on 3128 by default. Is that how the Windows version is set ? – Lawrence May 8 '14 at 6:18

Have you checked the firewall on your proxy server to make sure it's allowing connections from the Windows host as well as the Linux host?

This problem is caused may be due to add-ons related with proxy or software like spybot please disable or uninstall them. if still problem persists then reset your firefox. I hope this will fix the problem.
