this add on has changed my life, love it. it needs way more hype!!!

Great extension. This extension is the reason why Firefox is unique to all other browser compared to privacy.

I use this every day, it's invaluable for debugging websites as multiple users (e.g. where users interact) and Chrome has nothing like it - keep up the great work!

Best thing since sliced bread. You can create tons of independent containers. Especially useful with sites like Google news where I open it in one container then every news item in its own container. When I am finished reading the item, the container and all its cookies disappear.
Super for multiple logins on a single site simultaneously.

Beautiful security tab feature.
I recommend not using Auto mode, but using Alt+C to manually open tabs when needed.

Definitely go for anyone who using firefox. Convenient, easy to manage.

Best extension if you manage Office 365 accounts
