Move Tab Hotkeys is a Firefox extension designed to enhance tab organization through customizable keyboard shortcuts. This subscription-based tool allows users to easily move tabs left or right, or to the start or end of the tab bar using simple hotkey combinations. The default shortcuts include Alt+Shift+Left and Alt+Shift+Right for moving tabs, along with Alt+Shift+0 and Alt+Shift+9 for repositioning tabs at either end of the bar. Users can customize these hotkeys according to their preferences via the Options page, making tab management a seamless experience.

Additionally, the extension supports multi-selected tabs, allowing users to move several tabs simultaneously if enabled in Firefox's configuration settings. However, it treats pinned and non-pinned tabs as separate entities, meaning that movements involving both types cannot be executed together. This feature ensures that users can maintain a tidy workspace while navigating their browser more efficiently.
