Is it ok I’m getting notification about “Facebook Container” add-on when my Facebook is already running in a container using " Firefox Multi-Account Containers" add-on?
Because in the description of “Facebook Container” add-on I can see this note:
NOTE: If you are a Multi-Account Containers user who has already assigned Facebook to a Container, this extension will not work. In an effort to preserve your existing Container set up and logins, this add-on will not include the additional protection to keep other sites out of your Facebook Container. If you would like this additional protection, first unassign facebook.com in the Multi-Account Container extension, and then install this extension.
