I've tried tweaking my preferences to fix but nothing seems to work. Reproducible: Always Steps to Reproduce: 1. Install 1.3beta (custom install with no chatzilla or newsgroups) 2. Type any URL 3. Expected Results: connection refused when attempting to contact... My computer has an Insight cable ISP with a NetGear router. OS is XP-Pro. May be something that changed in the configuration of Mozilla from 1.2 to 1.3beta which I need to update a setting for but if so I can't find it.
Do you use a firewall like Zone Alarm ?
No firewall like ZoneAlarm running. The router has a basic NAT firewall but it doesn't seem to affect Mozilla 1.2 or Internet Explorer 6. I also checked the router settings and I didn't notice anything that should cause a problem but again it's possible I could be missing something. The strange thing is I can install Mozilla 1.2 and browse freely then close out and install Mozilla 1.3beta and get all connection refuses then install Mozilla 1.2 and everything works again all in the same session without opening/closing anything else.
Have you installed a firewall someday on your system ? It's possible that an old installation can cause this. BTW: NAT is for the browser invisible.. Please run 1.3b and while 1.3b is running open a cmd window and type : "netstat -n" Do you see 2 loopback connections like this ? : Proto Lokale Adresse Remoteadresse Status TCP 127.0.0.1:3869 127.0.0.1:3870 HERGESTELLT TCP 127.0.0.1:3870 127.0.0.1:3869 HERGESTELLT (The status is in german in my case)
Yeah, I got the loopback connections like that. I uninstalled an old firewall program I used to use and sure enough that was the cause and everything works fine now. Thanks for the help Matti.
