Been using Firefox for 80%+ of my use cases, but whenever I need to make a payment online, it is easier to just use Chrome which stores and syncs payment methods.

And I am amazed how Firefox doesn't have profiles unlike Chrome, or at least the implementation is so counterintuitive (I use "Personal" profile as a Facebook container for instance). On the other hand, Chrome profile switching and isolation are just still so good. I hope this is not some patent-protected thing which Firefox can't just copy for good.

If Mozilla team is reading, here is some direct feedback for why I couldn't completely switch over.
