Updated windows. Firefox gives "Problem loading page" error everytime now.

Question

my computer told me that windows updates were available and that I needed to restart so I did. When the restart was complete firefox doesn't work at all now. It jut gives me the "Problem loading page" error no matter what website I visit. I have tried removing it from my windows fire wall and re-adding it but that did not help. I also try to uninstall firefox and reinstall but that didn't help either.
I am using Widows 7 for what it's worth. Any help would be greatly appreciated!

Answer 1

Try these in order.
Type '''about:preferences#advanced'''<Enter> in the address bar.
Under '''Advanced,''' Select '''Network.'''
Look for '''Configure How Firefox Connects''' and press the '''Settings''' button.
Check the settings.
Some problems occurs when your Internet security program was set
to trust the previous version of Firefox, but no longer recognizes your
updated version as trusted. Now how to fix the problem: To allow
Firefox to connect to the Internet again;
* Make sure your Internet security software is up-to-date (i.e. you are running the latest version).
* Remove Firefox from your program's list of trusted or recognized programs. For detailed instructions, see

'''[http://www.mozilla.org/en-US/firefox/all/ Download Firefox Full Installer For All languages And Systems]''' {web link}
Save the file. Then;
Using your file browser, open the '''Programs''' folder on your computer.
'''Windows:''' C:\Program Files
C:\Program Files (x86)
'''Mac:''' Open the "Applications" folder.
'''Linux:''' Check your user manual.
Look for, and rename any Mozilla and Firefox folders by adding '''.old''' to them.
Now run the full installer.
If all goes well, remove the OLD folders when you are done.
