I recently updated firefox. Since updating now it will not open at all. It says it is not responding and wont restore a session or anything. All my important bookmarks was on this browser. I have tried deleteing and re-installing. I have also tried restoring the older version I have been using that was installed in March. What can I do to solve this problem. I dont like using Internet Explorer.

A possible cause is security software (firewall) that 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 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.
