TabStash saves all the tabs in your window into a single, organized page — like OneTab, but private by design.

FEATURES
- One-click stash: collapse a whole window of tabs into one page.
- Organize freely: group, rename, search, reorder and restore tabs. Drag to reorder or merge groups.
- Paste & import links: add links in bulk (one per line, or "title | url").
- Delete duplicates: clean a single group or every group at once (a duplicate = identical URL and title). Removed links go to an expandable Trash group so nothing is lost.
- Expandable Trash: open a trashed group to see its links and restore just one, or all of them.
- Encrypted local storage: your data is stored locally and encrypted (AES-256-GCM). No account, no cloud, no tracking.

OPTIONAL COMPANION TOOL
TabStash works fully on its own. If you want a portable, encrypted copy of your saved tabs outside the browser, an optional local tool can keep a mirror vault on disk. The toolbar badge shows whether the tool is connected (green) or offline. The extension never requires it.

PER-BROWSER VAULTS
If you use more than one Firefox-based browser, each one keeps its own separate vault, so their tab lists never mix.

PRIVACY
Everything stays on your machine. No remote code, no network requests, no analytics.

1.9.8
- Reliable sync with the optional local vault tool for very large collections: messages are size-bounded and streamed in chunks, so thousands of saved links (including single groups with 1000+ links) sync without dropping the connection.
- Change detection now uses polling instead of an unsolicited push, avoiding a rare disconnect on Windows.
- New: "Delete duplicates" per group and "Delete all duplicates" across all groups (a duplicate = identical URL AND identical title). Removed duplicates are moved to a "Duplicates" group in the Trash.
- Trash groups are now expandable: view their links and restore a single link or all of them.
- Robustness fixes for large vaults and concurrent writes.
