There may be arguments in favor of global menus, but browsers are not one of them. Personally, I detest global menus like the plague because it really disconnects the list of actions from what I'm going to be acting on, especially if you have e.g. focus follows mouse. (But I'm sure we're just supposed to let go of that too...)
EDIT: ... and since nobody asked: The problem with the Linux desktop is mostly lack of consistency across applications, IMO.
There is a part 6 entry addressing this very thing:

I do agree with the author on his sentiment on the lack of discoverability with applications nowadays. It might've been better to showcase the `chrome://settings` interface since it's a prime example of less suitable mobile design bleeding into the desktop UX. Funny, I just noticed that they actually use a proper hamburger icon for toggling the hidden settings menu, not the triple dots.
I think that by now, we're well on our way of educating people on the meaning of the hamburger icon...
