Sidebery vs Workona

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.

Workona is a collaborative web app for organizing browser work and gathering project resources from other apps into shared spaces. A space can bring together Google Drive folders, Slack channels, task lists, browser tabs and web links. Its optional tab manager organizes tabs into spaces, autosaves them and can restore past sessions for up to 90 days. Space templates can set up project resources, and Workona says Zapier can create content from 6,000+ apps. The integrations page lists Google Drive, Docs, Sheets, Slides, Asana, ClickUp, Monday, Trello and Slack; its help page says spaces currently connect to Asana and Trello among those task apps. Tabs in shared spaces stay private to each user. Workona works on Chrome, Edge, Firefox and Safari across macOS, Windows and Linux, with extensions for Chrome, Edge and Firefox. Individuals can use a free plan with limited spaces and sections. Team costs $12 a month, billed at $12 per user monthly, or $108 per user per year with annual billing.
