In their own words
Sidebery
Sidebery is a free Firefox extension for managing tabs and bookmarks in a sidebar. Its panels can display tabs, bookmarks, and browsing history, with tabs shown as a flat list or tree. Users can group tabs under custom names, color and sort them, and automatically unload folded branches or inactive panels. Container features bind containers to panels, reopen URLs in selected containers, and set proxy or User-Agent settings. The extension also supports tab search, session restore, suspension, workspaces, snapshots, and optional cross-device synchronization. Context menus, mouse and keyboard controls, drag-and-drop behavior, and sidebar styles can be customized with variables and CSS. Data is stored locally by default; Firefox Sync or Google Drive can sync selected settings and tab data. The project is MIT-licensed. Firefox does not permit hiding the native horizontal tab bar, and some tab-moving add-ons may conflict.
