Good Fences sɣur ejm3

Good Fences automatically routes every navigation to the right Firefox container. Define containers, assign domains, and the extension silently enforces those boundaries. No manual switching, no accidentally browsing Facebook outside isolation.

Unlike Mozilla's Facebook Container, Good Fences works with any domains you choose. Each container can hold as many domains as you want: group Facebook and Instagram together, Google and YouTube, Amazon and IMDb, or all your banking sites into one. You decide what shares a session.

Features

• Intercepts navigations from the address bar, clicked links, and external apps
• Each container can hold multiple domains, so related sites can share a session while staying isolated from everything else
• Subdomain matching built in: assign facebook.com and subdomains like www. and m. are covered automatically
• Per-tab redirect loop guard prevents infinite loops (a known bug in Facebook Container)
• Detects and blocks cross-container OAuth flows with a browser notification
• Containers are automatically recreated if you delete them from Firefox's container manager
• All extension-created containers are removed cleanly on uninstall
• No data collection, no telemetry, no cloud sync. Everything stays local on your machine.

Privacy by design

Good Fences is built for users who want full control over which sites share a session and which don't. It is a reliable, user-configurable alternative to single-site container extensions like Facebook Container.
