Container Windows

This addon is the thin, wobbly pillar on which my entire Firefox Addon tower is built, and my goodness does it do a great job. All it does is move your container tabs to the window with the MOST tabs of that same container. If a container isn't opened at all yet, it automatically opens a new window. It's that simple, but it is fantastic! In combination with addons that automatically open a domain in a window (such as the rules provided by Firefox Multi-Account Containers or Containerise), this means you'll be able to type in a domain, and have it be opened in a container, and be moved to the right window. Organizing your browser experiences into different windows, which is EXACTLY what I have always wanted. Open Youtube? Open it in the Media window. Open my work websites? Open it in the Work window. Everything organizes itself, no matter where you started. Add another addon like 'Auto Discard Tabs' and you can even make it automatically discard duplicate tabs after organizing itself. Everything happens super quick, and you'll barely even notice that your tab got moved. Even though using Containers on a per-window basis seemed like the most logical way to organize your browsing tabs, this is the only addon I could find that allows for that. And for that, I thank the developer wholeheartedly!

It's a simple tool that does what I need, and it does it well. I have another extension that sorts Google Drive/Docs URLs into a particular container, and then this extension has that container open in a separate window. It makes it feel like Google Drive/Docs are in their own "app" or browser. Very helpful for organizing windows and containers.
