ctrl_tabs автор Pablo Saavedra

Tired of using i3 and moving your hands all the way to your mouse
to change tabs in Firefox because the Alt+<tab_number> does not work?

This add-on is for you! Now you change tabs with Ctrl+<tab_number>.

New keyboard shortcuts you unlock with this add-on:

- Ctrl+[1-9] move to the tab number.
- Ctrl+Alt+0 move to the last tab.
- Ctrl+Alt+l move to the right tab.
- Ctrl+Alt+h move to the left tab.
- Ctrl+Alt+q close the current tab.

This add-on does not override the defaults Alt+[1-9] shortcuts.
