duplicating tabs in firefox is a common task, but it can be difficult to do without any add-ons. Here are some tips on how to duplicate tabs in Firefox without any add-ons:

  1. Open Firefox and click the three lines in the top left corner of the window. This will open a menu with three options: Add-ons, Firefox Settings, and Preferences.
  2. In Add-ons, select the option that corresponds to your browser version (for example, Chrome for Windows or Mac).
  3. In Firefox Settings, select the option that corresponds to your browser type (for example, Windows or Mac).
  4. In Preferences, select the option that corresponds to your preferences (for example, how you want Firefox to handle duplicating tabs).

There’s loads of add-ons that can help you duplicate tabs in Firefox, even copying all of the history to the new tab. What you might not realize, however, is that you can do the same thing without any add-ons.

To duplicate a tab, all you need to do is hold down the Ctrl key while dragging the tab to a new spot on your tab bar–you’ll see the little arrow show up, and you can drop the tab there. Once you’ve done so, you’ll see that the tab has been duplicated, including all of the tab history.
