Container Picker av jamesbond

Container Redirect lets you assign watched domains to Firefox's Multi-Account Containers. When you navigate to a domain on your watch list, the extension intercepts the request and shows a picker so you can choose which container to open it in — instead of the page loading in whatever container/tab you happened to click from.

Features:
• Add or remove watched domains from the toolbar popup
• A lightweight in-page picker to choose the container on matching navigations
• Works entirely locally — no accounts, no external servers

Useful for keeping work, personal, and other accounts cleanly separated across containers without manually switching every time.
