Firefox menu icons (at top) - how to change?
I have a 'Share' icon, a 'Google Drive' icon & something new and unknown, a double-page icon ... how to change or delete (even identification is not self-evident in the case of the last double-page icon) these icons? (they don't show up under the Add-ons submenu) Thanks
