MOSSU Tab Parking by akifumi

Park open tabs into a local session and reopen them later. One click saves a window, the active tab, tabs to the left or right, or every window. Search by title or domain, flag priority tabs, and name sessions. No account and no developer server.

Pinned tabs, private windows, pages still loading, and internal browser pages stay open. Restored tabs can remain in the list or be removed. Import OneTab lists or plain URLs, and export JSON anytime.

Saved URLs and titles stay in this browser. An optional bookmark folder can keep a recovery copy; if Firefox Sync is on, that copy follows your bookmarks. The extension never asks for an email or password.

An introduction page can play an embedded preview only after you allow youtube-nocookie.com. The same video is available as a normal link without that permission.
