Open in All Containers

Effortlessly split your browsing session across every container.

Overview
Stop switching contexts manually. With "Open in All Containers," you can launch any link or bookmark simultaneously across every accessible Firefox Container with a single click. Perfect for testing, multi-account management, or isolating sessions without repetitive tab opening.

How it works
Simply right-click any hyperlink on a webpage or any bookmark in your toolbar/library. Select "Open in All Containers" from the context menu. Firefox will instantly create a new tab for each container (e.g., Personal, Work, Banking, Shopping) and load the target URL inside each one.

Key Features

One-Click Bulk Launch – Open the same link in every container at once.

Seamless Integration – Adds a single, unobtrusive option to the native right-click menu for links and bookmarks.

Smart Container Detection – Automatically detects all containers currently accessible to your Firefox profile (excluding private/containers you don't have permission for).

Perfect for Power Users – Ideal for QA testing, managing multiple social media accounts, comparing logged-in states, or running parallel workflows.

No Overhead – Lightweight and script-free; uses only Firefox's native Containers API.
