Firefox the only browser that works?

[massappeal]

I'm having a really strange problem...

Since maybe a couple weeks ago Firefox is the only browser that works for me. Other browsers can't seem to connect to ANY website. I've tried Safari and Opera... they don't work.

I have:

tried several different wifi signals
reinstalled Safari, Opera, and Firefox
reinstalled OS X (archive and install)
repaired disk permissions

No matter what I do, Firefox is the only thing that works

also... Software Update and a few other apps (i.e. iScrobbler) can't connect either so I can't update OSX after the archive and install

Try opening Terminal and typing

ping google.com

You should see something like this:

Last login: Mon Jan 12 23:03:47 on console
Versailles:~ bluerevolution$ ping google.com
PING google.com (72.14.205.100): 56 data bytes
64 bytes from 72.14.205.100: icmp_seq=0 ttl=243 time=97.597 ms
64 bytes from 72.14.205.100: icmp_seq=1 ttl=243 time=80.089 ms

64 bytes from 72.14.205.100: icmp_seq=4 ttl=243 time=85.899 ms

The "64 bytes" lines will continue to repeat every second or so; just let a few of them come back and then stop the process by pressing control+C. If they don't appear at all or if you get a DNS error, something isn't right.

You don't have a proxy selected anywhere, do you? A great feature of Firefox is that it can find its way to or around a proxy if necessary.

You mean has an auto-detect function.
But, good idea to do a search!
