I am used to type Ctrl + PgUp and Ctrl + PgDn in many of my applications (firefox, terminal, thunderbird, ...) to navigate between tabs.

This worked fine in Thunderbird (to switch between emails and calendars mainly) until a recent update : when the focus is on the left pane showing my email accounts typing Ctrl + PgUp or Ctrl + PgDn scrolls down or up inside the folder pane instead of switching tabs.

I already spent hours trying to fix that without success mainly trying ad-ons. So my question is : does anyone know how can I remove this scrolling shortcut on Ctrl + PgUp or Ctrl + PgDn in the folder pane ?

  • Is NumLock on? Ctrl+PgUp and Dn work as you expect, changing tab, only when Num is not Locked. Nov 13, 2022 at 19:38
  • @DrMoishePippik with or without NumLock on, the behaviour is the same for me : If something is selected in the folder pane and it has focus, then the shortcut scrolls into this pane instead of moving to next/previous tab. Nov 13, 2022 at 20:02
  • Workaround: hit ctrl+k then ctrl+pgup / ctrl+pgdn

  • @1NN Thank you for the workaround. It's no perfect, but better than nothing :) So I guess you are able to reproduce the behaviour I described ? Nov 16, 2022 at 7:47
  • I can't reproduce this behavior at all : Ctrl+PgUp/Dn for me behave on both sides the same as PgUp/Dn. Ctrl has no effect. After Ctrl+K neither has any effect at all. Do you have any installed add-on that explains this behavior? Try it perhaps in Troubleshoot Mode Thunderbird.

You should be able to use the tbkeys addon.

The plugin is aimed at power users, so you'll need to consult the github page to check how to set up everything but adding these two lines in main key bindings setting should do the trick :

    "ctrl+pagedown": "window.document.getElementById('tabmail-tabs').advanceSelectedTab(1, true)",
    "ctrl+pageup": "window.document.getElementById('tabmail-tabs').advanceSelectedTab(-1, true)"
