Tab Stash

Free plan Extension

What Tab Stash is

Tab Stash is a free, open-source Firefox extension that saves batches of browser tabs as bookmarks for later restoration. Users can restore a single tab or a group, organize items into groups and sub-groups, rearrange them by dragging, and select multiple items. Stashes can be viewed in Firefox’s sidebar, popup, or a full-browser tab, with quick search for finding saved items.

Recently deleted items can be recovered; by default, they remain on the computer for up to six months. Import and export options include rich text, Markdown, OneTab, and other formats. Version 3.5 supports Firefox’s native tab groups, allowing tabs to move between open groups and the stash. Because stashed tabs are bookmarks, they can sync to other computers or mobile devices through Firefox Sync when configured. The extension has a dark mode that can follow the operating system setting or be switched manually. Its maker says user information is not shared with the developer or third parties except as described in the privacy policy, and stored items remain local rather than in the cloud.
