What Tab Stash is
Tab Stash is a free, open-source Firefox extension for saving batches of tabs as bookmarks and reopening a tab or group later. It organizes saved tabs with groups and sub-groups, drag-and-drop reordering, and multi-selection. You can view a stash in Firefox’s sidebar, a popup, or a full-browser tab, then use quick search to find saved items. Recently deleted items can be recovered; by default, they remain on your computer for up to six months. Stashes can be imported and exported in 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 saved tabs are bookmarks, they can sync to other computers or mobile devices through Firefox Sync when configured. Tab Stash includes a dark mode that can follow the operating system setting or be switched manually. The maker says user information is not shared with the developer or third parties except as described in the privacy policy; saved and deleted items are stored locally rather than in the cloud.

Verdict
