Tabs in the title bar is a better UI decision. The URL box belongs to the tab, so it should be part of the tab. Your objection here seems to be 'Firefox mimicked Chrome and this is a bad thing', rather than these things being objectively bad.

Those things are all subjective, plenty of reasonable and clueful people will disagree as to whether any of those are good or bad things (or neither). When you say something like...

"the influence of Chrome on Firefox has been universally negative"

...that's saying a whole heck of a lot more than, they made some UI decisions that were personally disagreeable to you but not necessarily to other people.

What operative system are you using? On GNU/Linux - http / https are visible in the url bar - tabs are under the url bar (and under any other bar you activated) - menu is still there - status bar can be toggled on/off

Lookup, did they hide the "https://? And why NOT hide the "http://? Oh, I see, You are kidding right? :D
