Hi John, are you referring to the item in the Firefox 138 release notes? https://www.mozilla.org/firefox/138.0/releasenotes/ - It mentions that typing ''weather'' in the address bar may display weather information on the address bar/autocomplete drop-down. It's not a separate toolbar button. If you meant an extension you installed from the Mozilla Add-ons site, check the Extensions button: [[Manage your extensions using the extensions button in the toolbar]]. Can you find it there? If so, hopefully you can pin it to the toolbar.
