Is there a way to hide Caption Titlebar (on the very top) in Firefox 57 (Developer Edition)?
I have been testing out the new Firefox 57 (Developer Edition) and for the most part I like what I see. However, that Caption Titlebar on the very top looks rather ugly and I would like to hide it as I have done on previous versions of Firefox. Unfortunately, there is no default way to do it. Also, the extension I've used before 'Hide Caption Titlebar Plus' has not been updated to work with the Firefox 57 and is currently in Legacy mode. Is there a way to do this now instead of waiting couple of months before that extension gets updated? Thanks in advance!
