Can't access the internet with Firefox

[tiffany26]

I installed Firefox 0.9.3 in a Dell running XP/SP2 with dial-up internet access set to dial automatically. Internet Explorer accesses the internet without a problem as does Outlook Express. When I start Firefox, it dials and gets as far authorizing, then I get the "access is denied, invalid username or password" message. In Options/Connections, Firefox is set to "direct internet connection" just like on my other computers but Firefox cannot access the internet because of the "invalid username or password" block. What could be the problem? I don't see any arrors in the dial-up configuration and IE and OE dial normally and connect. I have reinstalled Firefox but that did not solve the problem. I believe the error number is 631. Thanks, Tiff

Is there a firewall around your computer? If so, make sure Firefox has permission to connect. If you are using XP's firewall this might be of help: http://msdn.microsoft.com/security/p.../firewall.aspx

Set your Internet options to "never dial a connection" and dial up first with a shortcut to your dialup connection.
