I had previously made a request to make the Hotkey behavior equal to the Context Menu behavior on Firefox, and that Update works perfectly, Thank you.
Apologies for being "Nit-Picky" (I am very grateful for the previous Update). When moving Multiple Tabs, when Multiple Firefox Windows are Open, rarely do the Moved Tabs land on the Window I want them to go. After Moving the Tabs, only the Last Tab moved remains Selected (using the Hotkey, and the Context Menu). The User must then Re-Select their Tabs in the new Window to Relaunch the Move Function (which defeats the time saving purpose of using the Hotkey).
Perhaps this is not the goal for this Extension, where the main use-case is to move only one Tab. I fully understand if this Feature Suggestion is dismissed.
In any case, thank you for considering. Cheers!
