Multi-Account Containers Tools од DJS

Based on "Cookie AutoDelete" by CAD Team, "Exclusive Containers" by p3lim and "Container Bookmarks" by rafaelgomesxyz, this lightweight extension offers some key features to be combined with Firefox Multi-Account Containers:

main container cookies auto-delete
containers' domain isolation
container bookmarks' syntax support

Key features:

Opens cross-domain links in default container to prevent tracking
Auto-deletes cookies from the main container after last tab (containing that specific domain) is closed
Supports ContainerName+URL bookmark syntax

Please, notice that to enable the opening of a bookmark in a specific container, you must perform the following steps:
1) rename the bookmark url as https://www.domain.com/site#container-containername (for example: https://www.google.com/#container-Work)
2) register inside Firefox Multi-Account Containers a specific url (http://www.containername.container) to be always opened with a specific container (for example register http://www.work.container to be always opened with the Work container)
