Works great in general. If you are using containers combined with proxies or VPN, be advised that Service Workers ignore container settings. Hence, you might be generating traffice outside of the proxy/VPN you think you are using.

这简直就是我用firefox的唯一原因，这个插件太棒了

Used to be one of my favourite extensions to firefox. But after an update they've started asking whether a particular page should open in a specific container, very often every single time i want to open a page. Just give me an option to never ask for that, ever. If i want something to launch in a particular container, Ill just do it manually.

Very convenient to automatically open each of my websites in its own containers as defined in the configuration.

This extension keeps restoring deleted containers, which is very annoying if you've previously used Temporary Containers.

Excelente! Facilita muito meu trabalho, pois utilizo varias contas ao mesmo tempo

So far the best browser feature! And it's optional in form of extensions. Just take my money!
