Firefox has worked fine & now all of a sudden, it's stopped working. My Internet Explorer works, but I hate using it. Why & what do I do? Please help.

It is possible that your firewall or other security software 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.

I solved the problem by restarting my computer. I should have thought of that sooner. Duh!
