I restarted my Firefox this morning and it automatically updated to version 9.0.1. Since that update, I am unable to open Firefox - it is giving no response.

I restarted my Firefox this morning and it automatically updated to version 9.0.1. Since that update, I am unable to open Firefox. When I try to open it (and this is on a Mac), it does not respond and freezes with a white screen, the tab says "connecting...," and there are no bookmarks or anything showing on the browser. It does not respond at all - I cannot even click into the navigation to change any of the preferences. Please, someone help! Not having Firefox is killing me!

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.

Thank you for your response! The firewall on my computer is completely off, so there are no rules for Firefox. I appreciate your answer, but sadly, I'm still stuck.
