I have a black bar at the very top of my Firefox screen and in it are various sites I have previously searched. Some of them appear to be active as the logo beside them is turning around. I feel this may be slowing down my Firefox. Is it possible to delete this black bar?

The top bar is the Tabs bar (see attached markup of your screenshot). You can't delete the tabs bar, but if you do not need to keep the pages in those tabs open, you can close those tabs. For example, right-click (or on Mac, Ctrl+click) > Close tab.

Only 3 dots I see are the 3 colored ones. If those are the ones you are referring to please tell me what to do with them. I know the Red is for closing out and the other two have a purpose but I dont think those are the ones you are referring to? Please advise. Thanks.
