Works very well, until you need to temporarily disable it in order to troubleshoot a site's functionality. Disabling and re-enabling Containers causes ALL of your custom containers to be wiped, and you need to rebuild them all from scratch.

It a nice feature to be able to contain different services. But it is missing more controls. E.g. I don't see a option to be able to remove container association for a service.

proxy not work

There should be a shortcut to open a new tab in current container without using mouse.

Works as designed. Personally i don't use the "always open in container" feature, as i am using the same url with different logins in parallel, which would lead to a mess if I start using the feature. Keeping this limitation in mind, the tool does, what it is designed to do.

I am syncing with a Firefox account, but containers deleted on Computer A are restored when synced on Computer B, deleted on Computer B and restored again on Computer A, and so on, no matter how many times I delete them.
Also, since we are creating a large number of containers, it would be helpful to be able to search them in container management mode.

Needs to merge the "Containarise" and "Container proxy" add-ons features to become perfect.

Love this extension. However, lately, it seems Google can easily defeat the containers. I can't open more than one Gmail account at a time, unless I open the second Gmail account in a private tab. What's up with that?

Most usefull capablity of any browser I know. Please continue working on this.
It would be usefull to better sync between devices all the windows and tasks I have opend. Something like in Safari but with the container capabilities. That would be great.

I hope the extension can save the settings when it is deactivated. The current situation is that when the extension is deactivated by mistake and then activated, the new category settings in the container tab and the pinned tabs in the container tab will disappear, and the URL of the pinned tabs in the container will be lost without bookmarking.

This addon is really interesting and could probably be considered as a native feature in the future.
Nevertheless, potential users have to be aware that there are some known incompatibility issues at this time, such as the recurring login request when using Pocket (that can be solved by opening the submenu “Firefox Multi-Account Containers” and unchecking the submenu item “Always open in this container”).
