View All My Safari Extensions

Tab Duplicator adds a contextual menu item as well as a toolbar icon1 that will duplicate your active tab. By default it creates a new tab in the background, but it can be configured to make them foreground as well. You can also select tab positioning (first, last, before active tab, after active tab).

To install:

  • Download the signed extension and double click to install2

  • Right click and choose "Duplicate Tab".

You can view the source on GitHub as well! If you have suggestions for improvements let me know! Bug reports should be directed to the issues page.

Changes in 1.2

  • Added toolbar icon in addition to contextual menu. If you don't want it you can hold command and click and drag it off to remove.

  • You can now choose where to position your duplicated tabs. Choices are after current tab (default), before current tab, beginning, or end.

  • Optimized code. No more injected script.

  • Validation of events (disables button/contextual menu item if no URL is loaded)

Thanks to Brian Kim for the icon!


  1. You can hold command and drag the toolbar item off the toolbar if you don't want to use it!

  2. If you haven't enabled extensions in Safari then learn how.
