The Tab Suspender automatically monitors your browser tabs and suspends inactive ones to save memory and improve performance. When a tab remains inactive for a specified period (default: 40 minutes), it is replaced with a lightweight suspended page displaying the original URL and title. Click anywhere on the suspended page to restore the tab instantly.

What's New in Version 1.2
- Redesigned UI: A fresh, intuitive interface for a smoother user experience.
- Whitelist Functionality: Easily exclude specific tabs or sites from suspension via new whitelist buttons in the popup.
- ZZZ Animation: Added a playful "ZZZ" animation to visually indicate suspended tabs.
- SVG with Dark/Light Themes: Introduced SVG graphics with automatic dark and light theme support to match your browser.
- Bug Fixes: Improved stability and performance with various bug resolutions.

Key Features
- Smart Suspension: Suspends only inactive http/https tabs after a user-defined period (1-1440 minutes). The active tab and browser pages (e.g., about:config) are never suspended.
- Tab Protection: Optionally prevent suspension for tabs with:
- Audio/video playback (using Firefox’s native detection).
- Unsaved form changes (by comparing input values to defaults).
- Granted notification permissions (via Notifications API).
- Persistent State: Suspended tabs remain suspended after browser restarts until manually restored.
- Lightweight Design: Suspended pages use minimal resources, saving memory.

How to Use
1. Install the extension.
2. Click the extension icon to access settings.
3. Set your preferred suspension time (1-1440 minutes).
4. Configure protection options:
- Prevent suspension of tabs playing media.
- Prevent suspension of tabs with unsaved forms.
- Prevent suspension of tabs with notifications.
5. Enable or disable suspension as needed.
6. Inactive tabs will be suspended automatically, showing a simple page with the original URL. Click to restore.

Notes
- Suspension state is saved locally and persists across browser restarts.
- Feedback is welcome to help improve Tab Suspender!

Thank you for using Tab Suspender! This update enhances usability and performance to make your browsing experience even better.
