Finally found this! It baffles me how Firefox natively deals with Move Tab To End and Move Tab to Start using only the keyboard. This extension finally allows the user to specify a keyboard shortcut to simply move tabs to Start, End and also to Left and Right.

I so miss the older versions of firefox with the ability to manipulate the tabs any which way I wanted. This gives me some of that back. Probably the most important part. Thank you Moti Korets.

Thank you, these shortcuts are very handy. Standard Ctrl+Shift+PgUp/PgDn doesn't work on my Linux machine for some reason.

Perfect, exactly what I needed for long time. Thank you.

Simple and useful plugin! Would be nice to allow remapping keys to avoid conflicts with other shortcuts.

This is simple and effective. Solves a big problem for me.

Minor comment: I note that the 9 and 1 must be used on the keyboard only, while those on the numberpad do not work. Could this be added in the future?
