I know and I've done this, but the writing is on the wall.. It may disappear at some point and that just annoys me because it's really valuable IMO. It makes me unsure if I want to keep using it when that happens. If they aren't planning to remove it, why remove the UI button for it?

And it just looks so bulky with compact mode off. I tried to get used to it but no. I actually used it without compact mode before, but with the latest version the compact mode is using about the same vertical space as the old normal mode :)

> You can still re-enable X through about:config

Meaning X will be removed within ~three versions.

I didn't know/remember about this, just enabled it, great to know!

Now I have some extra vertical pixels :)
