The application FireFox 42.0.1 won't start. I can uninstall it and reload FireFox 37.0.2 and that used to work but now when I load 37.0.1 it actually installs 42.0.1 which no longer works. I had to use IE 10 to contact Mozilla. Yoy should be ashamed of this.. Can you tell me why Mozilla FireFox 42.0.1 installs but will not run? Also, why does FireFox 42.0.1 install when I try to install 37.0.2?

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.
