Most Recent Tab - Keyboard shortcut for last tab

Most Recent Tab is a Firefox extension designed to facilitate quick switching back to the previously selected tab. It offers a convenient keyboard shortcut (default: Control-Shift-1 on Windows and Command-Shift-1 on Mac) and a toolbar button to toggle between tabs seamlessly. This tool is ideal when comparing content between two tabs or quickly returning to a main tab after opening multiple links.

Originally developed in 2011 and updated to the WebExtension API in 2017, Most Recent Tab has been enhancing browsing efficiency for over a decade. Users can customize their keyboard shortcuts easily via the Add-ons list, making it flexible to individual preferences. Recent updates even allow jumping to the 2nd or 3rd most recent tabs, expanding navigation options. The extension’s source code is open and available on GitHub under Mozilla Public License 2.0, ensuring transparency and community collaboration.
