Why does Firefox give "Unsecured" error

I've recently built a new computer and de-activated some of the Windows features to make the computer run faster. When I installed Firefox, I continued to get a "This connection is untrusted" error message when trying to access any site requiring login information such as Google, Facebook and even Mozilla's site. When I do access these sites, images don't load and some pages appear as plain text as if there's no CSS file. Applications such as Gtalk won't log in, and I can't log onto MMOs I have downloaded through steam.

I've made a collage of the sort of errors I'm getting. Note that I've tried other browsers (Chrome) and gotten similar error messages.

Hi StormKatt

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 internet for Firefox and the plugin-container process and the updater process.
