## Description

The Tab Suspender automatically suspends inactive tabs after a configurable timeout to reclaim memory and CPU, helping your browser stay fast and your laptop battery longer. It replaces idle pages with a lightweight placeholder and marks suspended tabs with a visible indicator, so you always know which tabs are sleeping and can load them on demand.

Key features include: automatic suspension with a default 40-minute timeout, significant memory savings, native discard API integration for efficient memory handling, per-tab whitelists and protections for audio/video, unsaved forms, and pinned tabs, customizable emoji markers, pause/resume controls, and a seamless context-menu and keyboard-shortcut workflow. The extension also supports dark mode and a quick-load-on-click option for suspended pages.

## Review summary

Reliable and performance-boosting tab suspender with a clean UI and manual suspend option. It trims RAM by suspending inactive tabs and skips tabs with unsaved forms or media. Common drawbacks include distracting suspend notifications and the ZZZ indicator, a desire to exclude the active tab, lack of whitelist/export/sync features, and occasional compatibility issues or unexpected suspension of new tabs.

- Keeps browser snappy by suspending inactive tabs, reducing memory usage.
- Clean, intuitive UI that is easier to use than alternatives.
- Supports manual tab suspension for selective control.
- Skips tabs with unsaved forms or media, avoiding unnecessary suspensions.

### Cons

- Notifications pop up each time a tab is suspended.
- ZZZ icon/animation is distracting or obscures tab titles; lacks an option to disable.
- Cannot exclude the active tab from suspension; may suspend tabs you still need open.
- No built-in whitelist export or cross-device sync; difficult to share settings.
