Today’s tip is brought to us thanks to How-To Geek reader Konc.
First, use the Alt+D shortcut key sequence to move the focus to the location bar… and keep the Alt key held down.
Now simply hit the Enter key (since you’ve got the Alt key held down). This will open up the current URL into a new tab, basically duplicating the tab.
Once you’ve done it once or twice, you’ll realize that it’s extremely easy to use—just use Alt, D, Enter, and the tab is duplicated.
The same thing works in Chrome as well, and is the only way that we know of to duplicate a tab from the keyboard.
Note that you can duplicate a tab with the mouse in Chrome by simply right-clicking the tab.
Duplicate with Tab Mix Plus (Firefox)
If you are one of the many Tab Mix Plus users, you can always duplicate a tab with the context menu, or with the Ctrl+Alt+T shortcut key.
The nice thing about the Tab Mix Plus variety is that it’ll keep all of the history in the duplicated tab. Then again, that’s a lot of extra memory that Firefox doesn’t necessarily need to use, so you might prefer to stick with the first shortcut key if you don’t need the history.
