打开多个容器标签后，CPU和硬盘使用率会升高，CPU会占用50%，硬盘会一直有20Mb/s的写入，但并不会占用实际空间。

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

amazing extension!!

Awesome, except sync doesn't kinda work. Had to set up several times.

Very nice to have cookies in separate boxes. Noticed a glitch: if I right-click on the New Tab ("+") icon, and select "No Container", nothing happens! Selecting a container name opens a tab in that container. In contrast, long click on "+" icon, and selecting "No Container", opens a tab.

Strongly recommend also getting the Cookie Quick Manager extension for container-aware tasks like deleting cookies from a container, or copying cookies from one to another.

[EN] Add the option to display only cards from a given container, e.g. only from the "shopping" container.
Something similar to "Workspaces" in Opera.
[PL] Dodajcie możliwość wyświetlania tylko kart z danego pojemnika np. tylko z pojemnika "zakupy".
Coś podobnego do "Kontekstów" na Operze.

This is such an awesome feature of Firefox - I have several accounts under the same services that I regularly need to access, and this is the best way to make it work.
