Hello, Let me get a little more info about your issue. Do you have access to the address bar? If so, does it let you get to any websites? And have you tried restarting firefox and your computer?

Are you using the Firefox 33.0.1 version? *Help > About You can find the full version of the current Firefox 33.0.1 release in all languages and for all Operating Systems here: *https://www.mozilla.org/en-US/firefox/all/ ---- You can check if you can start Firefox in <u>[[Safe Mode|Safe Mode]]</u> by holding down the Shift/Options key. 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.
