Firefox "loads" but fails to display.

After updating Firefox, the browser loads (it shows up as running in Task Manager) but fails to display on screen. In other words, it is completely unusable. I've uninstalled & reinstalled the program, without favorable results.

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 internet for Firefox and the plugin-container process and the updater process.

I finally had to go back to an earlier version of Firefox. I couldn't determine that the anti-virus software program was the hindering culprit.
