A.) My problem was not ZoneAlarm, my Service Provider or my Computer.
My problem was Browser related.
2 Things I had done differently in recent times which I had to suspect to start first, were....I had recently purchased ZoneAlarm & Updated FireFox. So I had to start with these Apps first.
Anyway, speaking to my Service Provider, he told me to go to in FireFox..
Tools---> Options ---> Advanced ----> (Network Tab) ----> Settings ----> and check "No proxy"
Bingo!... sites like Facebook open everytime now!
Hope this helps someone in the future.
B.) You may need to reset firefox profile <== Click Here
and also double check that spyware infections have not compromised the system (or firefox).
Malware Clean-up Guidance:
C.) I solved the problem. ZA was not it. The culprit was one of my add-ons on Firefox (namely, DownloadThemAll).
I disabled the add-on and everything works fine now.
D.) Similar problem posted at mozilla support site that was resolved by doing the following:
Try a clean reinstall:
1. Download the Firefox installer from Mozilla.com and save it to your desktop or other location.
2. Make sure that Firefox is closed completely
3. Delete the Firefox installation directory (On Windows, this is typically the C:\Program Files\Mozilla Firefox folder that contains "firefox.exe" and other Firefox program files and folders).
4. Reinstall Firefox by running the installer you downloaded previously.
Your personal settings, including bookmarks and history, will not be lost.
