Burrow от Good Burrow

Some tabs are just for you. And some bookmarks, too.

Burrow keeps selected windows and bookmarks in a password-protected vault on your device. Open Burrow from the Firefox toolbar, save a window, then close its web tabs and lock the vault in one action.

Search saved windows by name, page title, or web address. Rename them, reopen one tab, or restore the whole window with its tab order, pinned tabs, and mute settings. Your saved copy stays in the vault.

Each vault has its own password, recovery key, folders, automatic backups, and appearance. Vault names remain visible while locked; saved contents are encrypted.

Download encrypted backups containing tabs and bookmarks. Test recovery keys and backups before you need them. Export standard bookmark HTML. The offline recovery kit opens downloaded backups without the extension. Local automatic copies do not survive extension removal or profile loss.

Free in Burrow 1.0: unlimited saved tabs, bookmarks, vaults, and folders, with search, encryption, restore, recovery, backups, export, and the Sage theme. A $9 lifetime key unlocks Warm, Midnight, and 8-bit themes and matching artwork. No plan-based storage caps; the same 500-tab per-operation safety guard and device storage constraints apply to everyone.

Burrow saves addresses and tab metadata, not page contents, unsent forms, or browser sign-ins. It does not lock Firefox itself or erase history, recently closed tabs, or network records. Normal web tabs only: private windows, containers, browser settings pages, and local files are unsupported. Finish forms and downloads before closing tabs.

No account, cloud vault, analytics, ads, or subscription. Firefox 142 or later.
