It sounds like the update files did not download all the way. That they became incomplete. It can happen if the internet connection gets disrupted.

Please try reinstalling Firefox, it will update any files that became damaged. You don't need to uninstall Firefox.

Download Firefox from here and open this file to reinstall Firefox: https://download.mozilla.org/?product=firefox-latest-ssl&os=win64&lang=en-US
