Tab Mix Plus is a very popular extension for the Pale Moon and Basilisk browsers that enhances tab browsing abilities. It includes such features as duplicating tabs, controlling tab focus, tab clicking options, undo closed tabs and windows, plus much more. It also includes a Session Manager with crash recovery that can save and restore combinations of opened tabs and windows.

Tab Mix Plus comes with Options window that includes all of its preferences as well as adding user interface to important Pale Moon/Basilisk hidden preferences. It is recommended that you make all changes to the preference in the options window. The options window is available from the Add-ons Manager or from the Tools menu (unless you turn this option off).

All Tab Mix Plus preferences stored in the prefs.js file in the user profile directory. These preferences can also be accessed and changed by entering "about:config" in the URL bar and "extensions.tabmix" in the filter box to narrow down the results from the search.

  • Enter "about:config" in the URL box and press <Enter>
  • Enter "extensions.tabmix" in the filter box to limit the results to Tab Mix Plus entries
