To enter tab search mode with your mouse, click the Firefox address bar once. At the bottom of the menu that appears, look for the “This time, search with” section and click the Tab icon (which looks like a blue-green tab or button).
Now you’re in tab search mode, and you’ll notice a small box that says “Tabs” at the far-left side of the address bar. Enter the term or terms that you’d like to search for. Immediately, you’ll see matching results pulled from all of your open Firefox tabs listed just below the address bar in a menu.
Click the result you’d like to see, and you’ll be taken to that tab immediately in whichever Firefox window is appropriate.
