''good4science [[#question-1282511|said]]'' <blockquote> I just added Malwarebytes Browser Guard but want to delete it because my Premium service already protects my computer. </blockquote> Hello good4science, I assume that you're talking about this add-on (?) : https://addons.mozilla.org/en-US/firefox/addon/malwarebytes/ You should be able to remove it when you go to the 3-bar menu => Add-ons => Extensions. There you should see the extension listed - on the right side you'll see three dots; when you click on them you'll get the option to remove the extension.
