Support for Firefox Containers
Firefox has a new feature called Containers, which is basically different "identities" by opening tabs that belong to one of 5 containers. This currently means that cookies are displayed more than once since they may be stored in each container. (The same issue is present in the native cookie edit window)
It would be great if the the Cookie Manager plus could support containers in the future (since that makes a great debugging tool when testing web pages with login).
Any references I could learn about this? I suspect the reason for duplicate cookies is they have different originAttributes (can you confirm that?). Unfortunately Mozilla's api doesn't allow change originAttributes without accessing cookies.sqlite database directly.
I have to say I have no idea how this is implemented, its probably a new property in the cookies db that distinguishes between the containers.
The feature is described here https://wiki.mozilla.org/Security/Contextual_Identity_Project/Containers
@alexlehm Cookies aren't involved, but it's Gecko. It's explained on the chapter An extended origin of your link. Also see How is Firefox able to Compartmentalize Containers? (the 8th answer in FAQ).
How could these Containers secure browsing when data as History and Saved Password are shared between them? Seems like there will a different Local Storage for every container, but it's a placebo for security improvement to me.
I am not so much using this for enhanced security, but its a killer feature if you are testing a portal and have to switch between a regular and admin user for example without using 2 different browsers
