the containers are great thanks for sharing, will definitely use those at home! You're right I should have emphasized the feel part of my comment since the dev tools especially are just a matter of preference. However I stand by my point that the profiles are definitely not on par with chrome, since there doesn't seem to be a way to have multiple profiles open at once.
I’m sure there are other ways to do this, including specifying a profile when you initially launch the browser, but you can enter about:profiles in the address bar to see a UI to manage the profile. One of the options is to launch that profile in a new browser.
If you just need a "personal" profile and a "work" profile, what I do as a workaround is to use normal firefox for personal and firefox developer edition for work. They are completely sandboxed from each other.
