Add Simple Tab Duplication to Firefox

Other browsers like Opera, Chrome, or IE let you duplicate tabs with the built-in functionality, and while there are plenty of Firefox extensions that provide this feature, if this is the only feature you want this might be the extension for you.


If you ever need to duplicate a tab in Firefox for some reason (i.e. e-mail) then you have to do it the hard way by manually opening a new tab and navigating to the desired webpage.



Duplication gets much easier to do once you add the extension to Firefox. Everything that you need is available in the context menu…choose the action that you need to perform and enjoy the simplicity.


Merging windows will be just as simple and quick.



There are a surprising number of options available for what seems to be a simple extension. Enable or disable setting to optimize the extension’s performance on your system.



The Duplicate This Tab extension provides a nice solution for anyone that has wanted the ability to duplicate tabs in Firefox.

    Use Tab Mix Plus to do this and a whole other cool tricks with your tabs.

    actually … why not just point to the address and then hit alt+enter to duplicate to new tab?

  3. Iszi

    Do you even need a plugin? I thought you could just Ctrl+Drag a tab to duplicate it?

  4. DrTeeb

    Iszi is right. Ctrl+Drag duplicates the tab in Firefox.

    This is already build in to firefox. Just hold the Ctrl key while pressing the refresh button on the toolbar – or middle-click the refresh button. Either way it will open the current window in a new tab (leaving the old tab alone).

    The more extensions you use, the more likely you’ll have issues. If all you want to do is duplicate a tab, do the following:

    Press Alt + D
    Continue holding Alt down but release D
    While still holding Alt down, press Enter (your current tab is duplicated)

    This works in Firefox, Chrome, IE, etc.

    Iszi said it: Ctrl+drag works fine.
