About browsers eliminating status bars and the like, I suspect that the stated reasons arenโt the real ones.
The claimed justification is that it โgives more space for the content.โ
Most likely the true reason for eliminating status bars is that it makes it more difficult for people to see what sort of calls the browser is making to which sites. For instance since I cannot exist online without status bars, I still see everything my browser is doing.

That will never connect because I have anything and everything to do with Facebook completely blocked.
Note that this attempted connection occurred on a page with absolutely nothing to do with Facebook. It was just attempting to track me, to load some useless Facebook widget, or most likely both at once.
The real reason that status bars have been removed is so that the users never notice (or notice less than they already did) when they are being surveilled.
