The URL is not valid and cannot be loaded.after install I get a message "the adress isn't valid" how do I fix this, please help.
Having used mozilla firefox for some time I had to re-install after some PC trouble, (I'm using Win WP) all I can get now after many times at re-install is a message stating that The address isn't valid & The URL is not valid and cannot be loaded.

Start Firefox in Safe Mode to check if one of the extensions ("3-bar" menu button/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem.
- Switch to the DEFAULT theme: "3-bar" menu button/Tools > Add-ons > Appearance
- Do NOT click the "Refresh Firefox" button on the Safe Mode start window

You can check for problems with preferences.
Delete possible user.js and numbered prefs-##.js files and rename/remove the prefs.js file to reset all prefs to the default value including prefs set via user.js and prefs that are no longer supported in current Firefox releases.
