Below is a listing of our top 15 favorite Firefox keyboard shortcuts. Learning these shortcuts will greatly improve your productivity and overall experience with Mozilla Firefox.
Ctrl+T and middle-click
Pressing Ctrl+T opens a blank new tab or if you want to open any link in a new tab press your middle mouse button (often the scroll wheel) to open that link in a new tab.
Oops, close a tab you didn’t want closed, press Ctrl+Shift+T to undo any tab close. Pressing this multiple times will undo multiple closes.
Ctrl+L or F6
Quickly get to the URL address bar by pressing this function key.
Ctrl+F or /
Pressing Ctrl+F opens the find feature. Using this you can quickly find text within the same page. If you want to do a quick find and have Firefox scroll to the text location as you type press forward slash (/) instead while in the browser.
Close the current.
Ctrl+Tab or Ctrl+Shift+Tab
Move between open tabs.
Open bookmark window for page currently viewing.
Ctrl+<plus>, Ctrl+<minus>, and Ctrl+0
Pressing Ctrl+<plus symbol> will increase the font size, pressing Ctrl+<minus symbol> will decrease the font size, and if you want to reset the font size back to the default press Ctrl+0.
Make the screen full screen, removing all toolbars and status bars.
Open the Download Manager window.
Jump to specific tab
To jump to a specific tab of the many you have open, press Command and any number key between 1 and 9. Ctrl-1 jumps you to your first (left-most) tab. Ctrl-5, for example, jumps you to the fifth tab from the left. Ctrl-9 jumps you to the right-most tab, so this keyboard shortcut is really only useful if your open tabs number in the single digits.
M for minimize
Hit Ctrl-M to minimize your current window. On Windows, use Alt-spacebar-N to minimize Firefox (or any active window).
Private, keep out
Hit Ctrl-M to open a Private Browsing window.
Forget the past
Hit Ctrl-M to clear your recent history. You can choose a time range of the last hour, last two hours, last four hours, today or everything. On Windows, make sure you use the small Delete key and not the Backspace key.
Mute noisy tab
Like Chrome, Firefox displays a speaker icon on any tab that is playing audio. Unlike Chrome, with Firefox you can click on the speaker icon to mute the tab.
