I use it all the time and have for years. Just seems like a weird feature to lock behind about.config and say it’s not supported while they still support things like Pocket.

It is essentially just extra maintenance of a feature in Firefox that (statistically) not many people use
As such, it’s marked as “unsupported” to make clear that if any issues arise, Mozilla won’t help you with those issues.
Not many people use it because it is hidden away and not default.
Firefox in compact mode is about as compact as Chromium, so no issue here.
I think I have it enabled too and just forgot about it. It really should be a checkbox next to themes or something.
