The
unofficial Mozilla FAQ says this:-
When I start Mozilla, no matter what I do- all I get is an error message that says: "The connection was refused when attempting to contact..." for any site that I try to reach?
Why is that?It sounds like Mozilla is either being blocked by a software Firewall (like e.g. Zone Alarm or Norton Internet Security) on your PC or you need to enter / modify the Proxy settings. The latter is the likely reason for the error message if your PC is connected to the Internet via a local network (LAN).
To get the correct proxy settings, you can either ask your admin / helpdesk or copy IE's proxy settings.
For an example how to find IE'S proxy settings, see here:
How to configure Internet Explorer's proxy settings
To edit Mozilla's proxy settings, select Edit -> Preferences -> Advanced -> Proxies. Enter the proxy settings for all fields if needed, but at least for:
- HTTP
- FTP
- Secure
If IE's proxy settings contain an automatic proxy configuration URL, you only need to enter that one in corresponding field for Mozilla.
Note: Problems like this may also be caused by Spyware / Adware that is on your system. If your PC is acting sluggish or slower than it should and Internet Explorer greets you with several popup windows even on sites that should not have them, it's an indication for Spyware / Adware on your PC. Please see This FAQ entry for more information.
