If you want to add similar functionality to Firefox, you can do so using an add-on called Supertab. After installing (no restart necessary), you’ll be able to cycle through your open tabs in most recently used order. You can customize the add-on so that it uses either “Ctrl + Tab” or “Alt + Tab”. You’ll probably want to use “Ctrl + Tab”, which is the default behavior, because using “Alt + Tab” is sure to interfere with it also being used on your desktop. You can also cycle through tabs in reverse order by including the Shift key (ie. Shift+Alt+Tab).
Just like “Alt + Tab” on your computer, as you continually pressing the shortcut, a new tab will be highlighted on the list. Once you let go of the keys, you’ll be taken to the tab that was last selected. If you have multiple windows open, it will only display tabs for the active window. This add-on is a great way to see a list of open tabs, especially if you have a lot of them open at once.
