Two things to check

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

Configure firewalls so that Firefox can access the Internet. {web link}

Google works, but the others don't ? ! ? !

I want you to start programs that can check it's home for updates. Do they work? Any program that accesses the web on it's own. One of them is Windows Update.

Start your Computer in safe mode. Then start Firefox. Try Safe web sites.

Starting The Computer In Safe Mode;

If running, turn your computer off. Remove any disks and thumb drives that are in your hard drives or ports. Now start your computer but also;

Windows; Press the <F8> key repeatedly. Mac: Hold down the Shift key. Linux; Using the command line, Linux/Unix computers can be booted into various run levels that determine which resources are loaded. For example, "runlevel 1" is typically the equivalent to Windows and Mac safe modes.

• Source; Safe Mode; Free Online Encyclopedia

When the Boot menu is displayed, release the key you were pressing. You must now choose what mode you want. The most used are;

• Safe Mode; The computer runs with only a minimum set of programs.
• Safe Mode With Networking; Same as above, but with internet access.

It is possible that your security software (firewall, anti-virus) blocks or restricts Firefox or the plugin-container process without informing you, possibly after detecting changes (update) to the Firefox program.

Remove all rules for Firefox and the plugin-container from the permissions list in the firewall and let your firewall ask again for permission to get full, unrestricted, access to install for Firefox and the plugin-container process and the updater process.
