Steps to reproduce:

In bug 1404337 there is a patch to hide the drag space on the left and right of the tab bar when the window is maximized.

I'm opening this bug mostly for discussion, as I'm not too invested either way, but I've noticed that this isn't consistent with Edge, which seems to be the only other browser that currently ships with a similar design.

When maximized, Edge leaves the drag space to the right of the tabs in place, and it can be double-clicked to restore the window (some people's muscle memory might be used to this, as opposed to hitting the restore button perhaps? maybe this is why microsoft left it there?).

Personally I think it makes sense to hide the drag space on the left, but maybe not the one on the right. One of the things I found interesting about Edge when it first shipped, is how bold Microsoft was in eliminating the titlebar completely, unlike Chrome which leaves a little bit at the top, but then I realized that since the browser initially starts with one tab, and it's intuitive to just use the empty space to drag the window, and then as the space shrinks when you open more tabs, the browser intuitively teaches you to just keep using whatever space "remains" at the right, which I thought was actually brilliant design in a sense.

By the way, in Linux, it's common for most window managers to allow you to click drag space in a window, and "drag" a maximized window, which instantly restores it and lets you move the restored window around, instead of first needing to restore, and then grabbing and moving as a second step. So even if it's decided that hiding it on Windows makes sense, it may still make sense to leave some drag space on the right of the tab bar on Linux.

Another Linux issue, and perhaps a little off-topic, but bug 1283299 seems to be nearing completion, and at least on Gnome it's the convention to not have minimize or maximize/restore buttons by default (this is configurable); whether Firefox wants to match this is a different subject altogether, but if this is desirable, then the double-click of drag space becomes the only way to max/restore the window.

Anyways, I think that's everything, discuss.
Ok, as is rightfully stating this was just sloppiness on my part because I really need to go on a weekend. This is going to be fun to uplift...

No problem :) take your time and enjoy the weekend :) At the end of the day there is still an option to back-out Bug 1404337 and Bug 1397265 I guess, and try to uplift only this one.
