Vertical Tab Keyboard Toggle Autor: Andrei M

A minimalist utility for Firefox's native vertical tabs.

Provides a quick keyboard shortcut to switch your tab bar between the traditional horizontal view and the new native vertical sidebar. Default shortcut is F1. Note that on many modern laptops (especially MacBooks or Dell XPS), you might need to press Fn + F1 unless you have "Function Lock" turned on.

How to change the shortcut:
* Type about:addons in your address bar.
* Click the Gear icon (⚙️) at the top right of the page.
* Select Manage Extension Shortcuts.
* Locate "Vertical Tab Toggle" and assign your preferred key/combination.

Requirements:
* Requires Firefox 142 or newer (where the native vertical tabs API is supported).
