Hi grrjr41, If you're using Gmail Notifier extensions, maybe one of these will help with Outlook... https://addons.mozilla.org/en-US/firefox/search/?platform=windows&q=outlook&type=extension

Hmm, where are the existing icons, exactly? The main toolbar normally has built-in buttons and add-on buttons, so to add a button there usually would require a new add-on. The (optional) Bookmarks Toolbar can contain bookmarks for any site, no add-on needed. More info: [[Bookmarks Toolbar - Display your favorite websites at the top of the Firefox window]]. You can pin tabs for frequently visited sites to the Tabs bar, and Firefox should re-open them automatically at your next startup. More info: [[Pinned Tabs - keep favorite websites open and just a click away]].
