An extremely powerful extension that allows you to have multiple accounts for the same service on Firefox. It's a great tool for separating your personal and professional life without having to use more than one browser. It's easy to set up, simple to use, and your containers sync across your Firefox account.

It makes so many things better. Even Twitter. This add-on is the only thing I've found that actually makes Twitter tolerable. That is saying a lot. Easy to use. Customizable. 5/5

we can't put multiple log-in in one container. we must separate the log-in into separate container

amazing extension!!
