310706 - Firefox won't load any pages; www.google.com could not be found, etc.

Status: RESOLVED INVALID

(Firefox :: General, defect)

Description

[Ingrid]

User-Agent:       Mozilla/4.0 (compatible; MSIE 6.0; Windows 98; .NET CLR 1.1.4322)
Build Identifier: Mozilla 1.0.7

I cannot get any pages or sites loading, using Firefox. I have used Firefox and 
IE for months without this problem. All of a sudden, a few hours ago, Firefox 
would not work at all. I uninstalled, reinstalled; I removed the profile 
information; deleted the Mozilla directory from Windows - still no joy. IE is 
working for me. I just downloaded Opera (because one site I visit won't load 
properly for me using IE - the URL is http://forums.vugames.com/forum.jspa?
forumID=160 - it loads, but I cannot actually reply to any topic as the text 
area fails to give me a cursor. It was fine with Firefox), and THAT doesn't 
work either.
I have Zone Alarm switched off. I haven't changed any settings. I use Symantec 
anti-virus - there has been an update for that today, but could that have 
changed something? I use Ad=Aware - full scan, no problems found.
I very much want to see this solved. It seems many other people have suddenly 
experienced this today...

Reproducible: Always

Steps to Reproduce:
1. Click onto firefox.exe.
2. Watch as the browser fails utterly to open any page at all.
3.

Actual Results:  
All sites, any sites, failed to open.

Expected Results:  
I expected, for instance, google to open when I typed in www.google.com Even 
typing in the actual numerical address of google failed to get the page up, so 
I don't think it can be DNS cache.

Only firewall I have is D-Link router, DI624+. I have not changed any settings. 
I haven't disallowed Firefox. Hard to see how it could be the router, when 
Firefox had been working perfectly fine for months on my computer.
I'm not the only person experiencing this problem - the support forum has quite 
a few people reporting the same thing.
