Tabernacle is a tree-style tab manager for Firefox that organizes browser tabs into folders, subfolders and nested trees accessible from the sidebar. It’s designed to keep related tabs together and reduce clutter by letting you open a single folder to view only its tabs; breadcrumbs show the folder path so you can move back up. The extension requires Firefox 142 or later and its source and installation are available on GitHub.

Key features include a global search that matches tab titles, URLs and folder names even inside collapsed folders; per-folder Firefox container settings or a default container to keep sign-ins separate; and pinned tabs that remain visible across every folder. Appearance options let you switch light/dark themes, display website domains and draw lines connecting nested tabs. A Recent activity view lists recently viewed and closed tabs and folders with timestamps and filters so you can quickly reopen or resume sessions. Overall, it focuses on hierarchical organization, session recovery and segregated sign-in management for power users juggling many tabs.

Do Frameworks Matter Anymore?

The importance of web frameworks is being questioned in 2026, as vibe coding and agentic programming shift focus away from implementation details. Frameworks mainly provide abstractions, structure, and constraints, but their significance may diminish as models and tools evolve, leading to more niche options or stability with existing choices like React.
