## Description

**Total Suspender** is a lightweight and minimalistic Firefox extension designed to improve your browsing experience by suspending all non-active tabs using Firefox's native `tabs.discard` feature. This reduces memory usage and helps keep your browser running smoothly.

Key features include a whitelist for URLs or partial URL patterns to prevent suspension of important tabs, the ability to ignore tabs that are playing sound, and a delayed suspend feature that lets you fine-tune when tabs should be suspended. Total Suspender requires only minimal permissions, focusing on storing its settings and managing filter URLs securely.

This extension is actively maintained, and the developer welcomes feedback and feature requests through user reviews.

## Review summary

Total Suspender is praised for its customizable suspension time, lightweight design, and simplicity, effectively managing tab suspension without complex permissions. Users appreciate its basic features but repeatedly request manual control over suspension and clearer visual indicators for suspended tabs. Performance issues appear when managing very large numbers of tabs, and some report higher memory consumption after installation. The extension could be improved by enhancing visual cues for suspended tabs and enabling manual tab management.

### Pros

- Allows customization of suspension time, including longer durations like two hours, unlike some other extensions.
- Lightweight and efficient, uses minimal permissions.
- Simple and easy to use with straightforward options.
- Effectively suspends tabs to reduce resource usage.
- Displays number of open tabs on the addon icon, although limited to 3 digits.

### Cons

- Lacks a clear visual indicator or notification of suspended tabs; users want icons or tab text to be greyed out or show transparency.
- Does not allow manual suspension or unsuspension of tabs, being fully automated.
- Has performance issues when handling very large numbers of tabs (thousands), leading to sluggishness.
- Some users report increased memory usage after installing the extension.
- Tab icons do not change when a tab is suspended, causing confusion.
