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 1.5
- Settings are synced with your Firefox profile.
- Allow exporting, importing whitelisted sites.
- Add keyboard shortcuts for suspend, unsuspend and whitelist.
- Add 'Ignore pinned tabs' option.
- Original website favicon is now displayed in suspended page.
- One-time migration added for migrating whitelisted sites from local to Firefox profile.
- Bug fixes and refactor.
