When I click on the icon to launch it, nothing happens. But when I launch the task manager, it says it is running but it never shows up as a browser. What's up with that? Basically then, it is only running in the background and not where I need it to run.

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.
