You can't do it. Add-ons are independent of containers. Furthermore, in Firefox one extension can't control other extensions.

Thanks by the answer, Then, is best open webapp bank in a private browser to best security practice?

You can turn off extensions for private windows, so yes, you can use it.

Note that containers do not work in Private Browsing mode, so it is either use containers if you want to separate data like cookies or use PB mode that uses a separate cookie jar shared by all PB mode windows.
