Alternative RuneScape Gamebar by Ben L.

In the current version of this extension, you can check on Grand Exchange offers and Distraction/Diversion readiness. The icons change appearance depending on what their statuses are - for example, the Grand Exchange icon will have a green check mark if an offer has completed while you were logged out. Click on an icon to open a small panel with more information.

If you previously installed the official RuneScape Game Bar and don't want your address bar to go to Bing, go to about:config and search for and delete keyword.URL.
