In Orion even if I create separate profiles, if I try to sign into 2 different accounts on the same site on different profiles, the first profile gets overridden getting logged out of the first account and into the second account; there is only one account active per site across the entire Orion browser even across separate profiles. They must be sharing cookies or something. I would like the separate Orion profiles to be more strongly separated. This way I can stay signed in simultaneously to 2 different GMail accounts or 2 different Github accounts, etc., (personal vs. professional) on the same device and using Orion as my only primary browser, by having 2 or more windows open that are set to separate Orion profiles.
Chrome profiles work in the way I described. If I have 2 Chrome windows open with separate profiles, I can be signed into separate GMail and Github accounts on each one. Firefox provides similar support with container tabs, which is even more powerful since it supports separate tabs in the same window that are scoped to separate containers having the same site open with different logins.
