Extensions that do not have a "Remove" button are installed globally by other software and are not under control of the Firefox extension manager. Globally installed extensions are usually found via a registry scan or are installed in a location that Firefox scans for installed extensions. *https://developer.mozilla.org/en-US/Mozilla/Add-ons/WebExtensions/Distribution_options *https://developer.mozilla.org/en-US/Mozilla/Add-ons/WebExtensions/Distribution_options/Add-ons_in_the_enterprise Extensions installed globally need to be removed via the settings (Options/Preferences) of the program that has added this extension or this program has to be uninstalled via "Control Panel -> Programs". In Firefox you can only disable such an extension. You can find the install location of a specific extension in the extensions.json file in the profile folder. You can open the extensions.json file in the Scratchpad and search for this extension. The path field lists its install location.

Solution was clear, concise and easy to follow. Thank you so much, I have my sanity back! Also appreciate the additional recommendations to ensure it was removed.
