On desktop-firefox, there are profiles in about:profiles and now there is a new entry in the menu with profiles but these profiles don't show up in about:profiles and the menu-profiles are like a sub profile of about:profiles-profile.

I can find this https://blog.mozilla.org/en/firefox/profile-management/ but I can't find anything regarding the differentiation of them and are the old about:profiles-profiles going to be discontinued? what is the difference?

Yes, they are separate. If you are talking about the new profile manager and the "old" about:profiles one, they are separate sets of profiles and cannot see each other's profiles.

If I remember correctly, the about:profiles data is stored in folders, while the new manager uses an sqlite database.

Thank you! Do you know why there are two, or what the difference is?

i have the same question. Trying to understand if I should switch over to the new profile system

[–] illusionist@lemmy.zip 1 points 4 days ago

The new profile setting can't have two profiles with the same account ...

I use the same account to keep bookmarks in sync. I hope they don't deprecate the old one
