I gave up on containers in Firefox a while ago. They didn't really support subdomains, which made using some services (e.g., AWS) extremely painful. Any site with a different subdomain for the login page, the auth flow, the dashboard, etc., became unusable. Don't know if they ever fixed it to allow for grouping subdomains.

I didn't find that unusable...you just have to add all the sub domains to the same container. Usually it isn't very many.

I use the "no container" default for work stuff, which means everything just works normally. Anything that isn't a tool for work, that gets a container.

I use Containerise[0] (not affiliated) exactly for that purpose but I agree, this should really be included in the official plugin.
