I get a "URL is invalid and cannot be loaded" message, and will not load any web pages
I use Firefox to get onto the internet but when the Firefox page comes up I get a small pop up on the screen that says "URL is not valid and cannot be loaded". I try to type what I am searching for in the google or yahoo search bar and this same pop up still occurs. I cannot go on any websites at all. Help!

Start Firefox in Diagnose Firefox issues using Troubleshoot Mode to check if one of the extensions is causing the problem (switch to the DEFAULT theme: Firefox (Tools) > Add-ons > Appearance/Themes).
- Don't make any changes on the Safe mode start window.
- https://support.mozilla.com/kb/Safe+Mode
If it does work in Safe-mode then disable all extensions and then try to find which is causing it by enabling one at a time until the problem reappears.
- Use "Disable all add-ons" on the Safe mode start window to disable all extensions.
- Close and restart Firefox after each change via "File > Exit" (Mac: "Firefox > Quit"; Linux: "File > Quit")
In Firefox 4 you can use one of these to start in Safe mode:
- Help > Restart with Add-ons Disabled
- Hold down the Shift key while double clicking the Firefox desktop shortcut (Windows)
