About this add-on

Tab Utilities is a light but featureful extension for tabbed browsing. This add-on replaces the original extension which may no longer be maintained.

Please remember to disable the old Tab Utilities add-on if you have it installed.

TUP 2.1.2:

Update compatibility to Pale Moon 32. Resolution of issues listed below still pending.

TUP 2.1:

This is an "emergency" release to support Pale Moon 28. Please read the "Known Issue" and "Workarounds" sections below!

Known Issue:

  • The Tab Groups' tab twisty icon does not show up, I have been unable to determine why.


  • The keystroke [Ctrl][Alt]-[+] will expand the current selected tab group (or all tab groups if none are selected or the current tab group is already expanded)
  • The keystroke [Ctrl][Alt]-[-] will collapse the current selected tab group (or all tab groups if none are selected or the current tab group is already collapsed)
  • Right click on a tab group tab, under the "Tab Stack" submenu select "Expand Stack" or "Collapse" stack as needed.
