Tab Shortcuts - Pinned & Unpinned автор SAGYO

Allows you to have a different set of hotkeys for pinned and unpinned tabs.

• Navigate unpinned tabs with Alt+Number by default.
• Pinned tabs have no new shortcut by default.

Change the shortcuts from: about:addons > ⚙️ > Manage Extension Shortcuts

You can assign Ctrl+Number as hotkeys but behaves a little strange as it will use first the browser's default shortcut and then the new one instantly.
