What homepage are you using?

Thank for responding. I'm using Firefox v. 136

I'm not sure what happened to your toolbar layout. However, here are some suggestions: (1) Home button You probably can find this in the box of available buttons on the Customize panel. From there you can drag and drop it to your preferred spot on the toolbar. (2) Bookmarks Were you accessing your bookmarks on the Bookmarks Toolbar, below the main toolbar? Or from the optional top Menu Bar? Or using a toolbar button that summons a drop-down menu? Or the sidebar? Feel free to try any of these: * [[Bookmarks Toolbar - Display your favorite websites at the top of the Firefox window]] * [[Restore the Menu bar in Firefox]] * There is an optional bookmarks menu button for the toolbar (<img src="https://assets-prod.sumo.prod.webservices.mozgcp.net/media/uploads/gallery/images/2021-06-19-21-15-40-ba2c56.png">) you can add using the Customize panel * [[Use the sidebar to access tools and vertical tabs]] (3) Sterile appearance It sounds like you lost your theme. You could check the current themes list, and consider a new one. [[Use themes to change the look of Firefox]]. Are we getting closer? As for what happened, did Firefox ever mention doing a Refresh/Tuneup or creating a new profile?
