> Bookmarks sync well (yay!) but don't always retain the same ordering on each device, which gets a bit confusing. I can work around this easily enough, but it's not quite as smooth as the same feature on Chrome.

I have never had an issue with bookmark sync on Firefox. I did with Chrome-my bookmarks order would be rearranged every time I changed something, other devices would be messed up. It is one of the biggest reasons why I stuck with Firefox all these years.
