I'm on a personal laptop, a Toshiba Satellite L305 running Windows Vista SP1.
I bought the computer about two months ago and, until about two hours ago, I had been using Firefox with no incidents whatsoever. I was browsing the internet this evening when it froze up. I force-quitted firefox.exe via the Task Manager and, as usual, restarted the application.
When I did so, it went through a round of auto-updating at the beginning (I had been running 3.0.11; it updated to 3.0.12, I believe) then, when the browser came up, none of the pages would load, returning a "Problem loading page"/"Unable to connect" message on all the tabs. I have tried to connect to several pages in FF, and none load.
My internet connection is fine - AIM, MSN, and Internet Explorer all work with no problems.
On a hunch, I downloaded Google Chrome and tried to run it - the same error occurred as in Firefox.
Yes, I have checked both the Windows Firewall and Firefox proxy settings. All are fine.
No changes have been made to my wifi, router, or ISP.
I've tried several levels of troubleshooting, all to no avail:
1) Restarted system.
2) Restarted firefox in Safe Mode.
3) Restarted Windows in Safe Mode with Networking
4) System Restored to a point made yesterday; then System Restored to a point made a week ago.
5) Upgraded firefox to the latest version, 3.5.1
6) Downgraded firefox to the last version, 3.5.12
7) Did a complete uninstall of Firefox (all profiles/preferences) and reinstalled to 3.5.1
8) Ran several antivirus/antimalware programs: SUPERantispyware, Malwarebytes' Anti-Malware, and CCleaner.
Googling the problem brings up several hits, but no clear resolution other than suggestions to check the Firewall and Proxy. Any suggestions would be incredibly helpful - I'm on an extended trip overseas, so I can't go to my normal tech support buddies for them to give it the once-over.
