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.

Nice.

Four stars (one less than five) only because 'Move Tab Hotkeys' seems to offer a broader range of options …

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

Move tab to the first spot does not work if any cards are pinned.

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

This plugin works almost perfect for me...would be cool if it could have some kind of animation though.

Great addon!

I truly need an addon like this because I have modified userChrome.css to get multiple rows of tabs with vertical scrolling instead of horizontal scrolling. After this moving tabs using mouse (standard way in Firefox) got broken. So addons like this is the only way for me to move tabs.

Also toolbar buttons for moving tabs would be great not to disturb keyboard and not to interfere with other functions of same key combos.

Also this addon seems not always work correctly with newly opened tabs when used in combination with "Simple Tab Groups" addon. I found out that "Move Tabs" work unstable with tabs I opened since I switched tab group. After I switch tab groups and before I open any tabs "Move Tabs" works correctly. So switching to any other group and back to group of interest is the workaround.
Please try debugging this situation. Thank you!

CTRL + SHIFT + Left and CTRL + SHIFT + Right shortkeys are working, but CTRL + SHIFT + 1 and CTRL + SHIFT + 9 are not working. Instead, the builtin CTRL + 1 and CTRL + 9 shortkeys are triggered.
Even after restarting Firefox... I'm using Firefox 54.0.1 64-bit and 58.0.2 64-bit, I get the same behavior on the 2.

"Move Tabs" uses four key-combos rather than buttons, and it moves only the selected tab. Two of the combos move the selected tab one place to the left or right, which my mouse cursor can do. Of the other two, Shift+Ctrl+1, or "Move The Tab All The Way To The Left," activates a different add-on (Nimbus Screen Capture) on my PC. There's no option to change the combo, nor one to select multiple tabs and move them all with a click.

The fourth combo, Shift+Ctrl+9, or "Move The Tab All The Way To The Right," works just fine.

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?
