Toggle Native Tab Bar от Irv66

Toggle Native Tab Bar gives you complete control over your browser's real estate. Whether you prefer the classic horizontal layout or the new native vertical tabs, this extension allows you to toggle that bar on and off instantly whenever you need it. It is the perfect companion for sidebar extensions like Tree Style Tab.

Advanced Support & Customization:
* Native Tab Support: Fully compatible with both standard horizontal and the latest native vertical tab features.
* Dynamic Icon Coloring: The toolbar icon automatically matches your browser theme colors for a seamless, native look (requires a simple one-time manual setup).
* Quick Access: Right-click the extension icon for instant access to setup instructions and settings.
* Theme-Responsive Design: Options and setup pages automatically adapt to your browser's Light or Dark mode.
* Clean, Minimalist Design: Modernized icons that visually represent the current state of your workspace.

Core Features:
* Instant Toggle: Show or hide the native tab bar with a click or keyboard shortcut (Ctrl+Alt+T).
* Companion for Sidebars: Designed to work perfectly alongside your favorite vertical tab managers.
* Per-Window Control: Choose to toggle the tab bar globally across all windows or on a per-window basis.
* Session Persistence: Your toggle states are automatically saved and restored when you restart Firefox.
* Flexible Configuration: Choose whether to keep the native window control buttons (min/max/close) visible even when tabs are hidden.
* Performance Optimized: Extremely lightweight with zero impact on browser speed.

Important: Setup Required
Because Firefox does not allow extensions to hide the tab bar directly, this add-on requires a small amount of one-time setup:
1. Enable userChrome.css support in your Firefox profile.
2. Add a few lines of CSS to your userChrome.css file.

Clear, step-by-step instructions (with copy-pasteable CSS) are provided immediately upon installation and are always available in the extension's options page.
