Hi Mozilla community, I have the Firefox Multi-Accounts Containers addon installed and configured to use separate containers for different critical websites. I've observed however that Firefox doesn't automatically load subdomains in the same container set for the main domain. Example: Container set for https://domain.com Domains https://www.domain.com and https://domain.com/us are not recognised to load under the container for domain.com. I have to manually set every single subdomain to also load in the same container. Theres no way I've found to do this automatically. All help, comments and feature request welcome in this regards. Thank you all! Joan.
