I just allowed FireFox to update itself. Now the version is at 25.0.1

Running on Windows XP Pro version 2002 SP2. FireFox has ALWAYS worked. NOW IT DOESNT. I can't even use it to connect to my own router login screen. IT IS DEAD.

RESET DID NOT WORK

SAFE MODE DID NOT WORK

What the F*** happened?

hello supercommando440, normally such issues are caused by a firewall/security software which doesn't recognize & therefore blocks new firefox versions: Fix problems connecting to websites after updating Firefox

2.Remove Firefox from your program's list of trusted or recognized programs, then add it back. For detailed instructions, see Configure firewalls so that Firefox can access the Internet.

The detailed instructions go into firewall config bs. HOW DO I remove Firefox from my program's list of trusted or recognized programs? What does this have to do with Firewalls? Why is this happening in the first place? Can I revert to an earlier version. My Firewall is OFF. These instructions suck.

So in otherwords, if my firewall is ALREADY OFF, removing and adding Firefox is completely pointless. So now I can no longer use Firefox? Ridiculous.

From now on, I plan to turn OFF FIREFOX automatic updates on every computer I ever touch. COmplete and utter BS.

In cases like this you can try to boot the computer in Windows Safe Mode with network support (press F8 on the boot screen) as a test to see if that helps.
