This seems a bit weird as containers still share history and other data between them. I get that they're not supposed to replace profiles, but this feature seems more suited to a per-profile basis than per-container because of said leakage. Of course, you can already do per-profile VPNs via split tunneling and a --profile specifier on startup, but it'd be nice to have a better UI within Firefox itself for the idea.
