I just uninstalled firefox for personal use at home (Still use it for work). I tried to change now given chromium is about to be neutered with ad blockers etc. This was my feedback - Extremely disappointed and non-functional profile option/s. Wanted to provide feedback that hopefully someone sees, as there is going to be a mass migration to FF soon and if they do NOT fix the below, people will give up fast. ''"There is no basic multi profile support like in edge, chrome etc. which is shocking. about:profiles is completely useless, because once you sign in with the same firefox account again, it just syncs to the same profile. Firefox MUST have multiple profile support under 1 login, not combine them. The thought of having to sign up a completely separate second account/email for a second Firefox 'account' with a second 'mfa' token just to separate personal and work is ludicrous. I want to sign in, pick my profile as personal / work and then it syncs my diff favourites, plugins etc. per profile for work or personal depending where I am, NOT SHARE them all on 1 login. This is not possible and a huge disappointment considering these features are considered basic in other browsers."'' Until firefox does this, it is unusable for multi work/private profiles and signing up a second Firefox account is just silly.
