Firefox 132.0.1 (64-bit); Fedora-40; Gnome. I just added the "authenticator" extension (https://addons.mozilla.org/en-US/firefox/addon/auth-helper/?utm_source=addons.mozilla.org&utm_medium=referral&utm_content=search). I would like its icon to appear in the toolbar, along with those for NoScript, Simple Translate, and others. I tried following the instructions on this page: "https://support.mozilla.org/en-US/kb/extensions-button". But clicking the "gear" icon in the toolbar brings up a list of all installed extensions, and there is no "gear" icon next to any of them. How do I add the "authenticator" extension's icon to my toolbar where the other extension icons are?
