Sync-able Firefox Profiles

[Dupe-boule-bagp]

It would be beneficial to have the capability for profiles to synchronize across multiple computers.

Specifically, I am interested in establishing distinct work, personal, and study/school profiles, each of which I would like to seamlessly synchronize across different instances of Firefox on various computers. This synchronization should include bookmarks, open tabs, browsing history, add-ons, and other relevant data.

Additionally, the inclusion of an option to opt out of synchronization would be highly appreciated, especially in situations where I prefer not to have my personal profile synchronized with my work computer.

All of these features should be accessible through a single Firefox account/login.

And it should be easy to switch between profiles.

And containerize them so they don't know about each other.

@Jon Thanks for merging the threads. 

The new Profiles feature is great! 

It would be great if copying the existing profile was the default behavior. I've spend too much time re-customizing my new profile when I could have copied. But I'll accept user error on my part. 

Creating a new mozilla account for each profile seems very counter-intuitive for a few reasons. That introduces bloat on the user for 3x times the logins even if you have a password manager. Also, who has 3x the emails just laying around. While it might boost Firefox user metrics, it would also make the numbers less reliable since they are inflated. 

I understand there are technical reasons why this might be hard, but I will say the Profiles feature has been amazing for separating Work, Home, Volunteer project #1, and Volunteer project #2, while keeping them easily accessible. 

Keep up the good work Firefox team!!
