I'll have to check, a cursory look at the documentation definitely makes them seem viable. Those definitely weren't a thing last I checked lol. As for the use case, I have a profile for job 1, 2, personal, and personal 2 (2 being a separate Google account for it's collaborative stuff).

For the most part it should do the trick. I dislike the branding for Mozilla VPN, but I see in the screenshots I can set custom proxy settings which will be nice.

As one of my profiles has a unique set of bookmarks and unique extensions, I'd probably be able to use the containers to substitute what I'm using 3 profiles for right now, and keep a separate profile for the job with unique extensions.

Thanks! Will definitely start migrating stuff over and seeing how it is. If I can still self host the sync backend I'll do that as well.

I don't know of any other browser that has the temporary container notion that FF has.
