Tab Stack is a lightweight Chrome/Chromium extension that lets you collapse a busy window into a clean saved list, then restore tabs later — individually or all at once. This also saves memory from having many browser tabs/windows open.
No accounts. No cloud sync. Just quick tab control stored locally.
- ✅ Save tabs per-window into timestamped stacks
- ✅ Restore into the same window (no chaos of new windows)
- ✅ Merge stacks (merge all, or merge by window)
- ✅ Auto-excludes pinned tabs + internal browser pages
