## What it is
The Marvellous Suspender is a free, open-source Chrome extension that automatically suspends inactive tabs to free memory and CPU, based on the original The Great Suspender. It is cleaned up, ad-free, tracking-free, and actively maintained with Manifest V3 support.

## Use cases
- reduce chrome memory usage from too many open tabs
- automatically suspend inactive tabs after a timeout
- recover suspended tabs after a browser crash
- suspend tabs when laptop battery is low
- replace the great suspender with a maintained fork
- make suspended tabs lightweight with screenshots or text-only previews

## When to choose
- you use Chrome 110+ and want a Manifest V3 tab suspender with no ads or tracking
- you want automatic tab hibernation with granular control over appearance and wake behavior
- you need session recovery of suspended tabs after crashes

## When to avoid
- you use a browser other than Chrome or Chromium-based browsers
- you need to keep web apps always active in background tabs
- you rely on Manifest V2 extension features
