Sidebery vs Toby

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.

Toby is a browser-tab and link organizer for collecting web resources and returning to them later. Users can make a Space for a project, team, or idea, then sort its tabs and links. One-Click Save captures all open tabs for later organization. Search finds pages across Spaces by title, link, or note, and Smart Sort groups related tabs for review. Users can invite teammates to shared Spaces, where members can add and arrange links, or share a collection through a link that anyone can view. Toby also saves Chrome tab groups as collections and syncs changes to those groups; that feature is limited to Chrome. The service lists Chrome, Firefox, and Edge availability, along with Android and iOS apps, and supports Google Sign-On. Toby says it stores account tabs and lists but does not track sites visited. The free Starter plan allows up to 60 saved tabs; existing tabs remain viewable, openable, and exportable over the limit, but new ones cannot be saved until the total is reduced or the account upgraded. Pricing is Free, or paid from $4.50/mo (annual).
