Sidebery
Firefox sidebar for navigating bookmarks alongside tree-style tabs, panels, history and saved snapshots.
Meet Sidebery
Sidebery adds a configurable sidebar to Firefox that combines tab management with direct access to bookmarks. It supports tree and flat tab layouts, panels, search and snapshots, helping users keep a working research session visible without abandoning the browser's own bookmark collection.
This is a browser-local productivity extension, not a hosted cross-platform bookmark service. It is most appropriate for Firefox users who want bookmarks and tab organization in one interface; its documentation also notes that interactions with other extensions can require troubleshooting.
