I wish Firefox would support faster profile switching. I consult and have multiple customers who all insist I use their Gmail or Outlook accounts, so I need about 6 profiles on the go. I can't use containers because it means I can't default, for example Google to my Personal container, which I want in my standard profile.

Having to create shortcuts to load each profile or keep about:profiles open is frustrating compared to the Chrome experience.

It's not enough to stop me using FF as my daily driver, but it is enough to stop my partner using it for theirs.
