SavePack von siq

Tabs you're not using right now shouldn't have to stay open. SavePack lets you snapshot any set of tabs, close them, and bring them back exactly when you need them — without bookmarks folders or session managers getting in the way.

What you can do:
- Save tabs into named packs, with optional tags for organisation
- Reopen a whole pack in the current window, a new window, or a Firefox container
- Group related packs together and collapse them out of the way
- Pick tabs individually or grab everything open at once
- Star packs and links to keep the important ones at the top
- Search across all your packs and links instantly
- Export and import packs as JSON — for backups or moving between machines
