Counter-points:
1. At the time, Firefox’ total installer size was ~4-5MB.
2. Much lighter than the contemporaneous IE8 and default Firefox skin, but it just came down to removing the menu-bar and status bar. Chrome’s lack of a traditional menu-bar put me off for a while, I’ll admit. I also disagreed with Chrome having its own visual-style on Windows instead of using the system theme. I know Chrome integrated with Aero Glass on Vista-and-later, but I was an XP hold-out until 2013 when I jumped to Windows 8.1.
3. “Dynamic” is overselling it. Internet Explorer had an auto-hiding status bar since version 4, albeit only in full-screen mode.
4. How is that a good thing? It wastes a thick line of screen space if you downloaded a single file. I preferred Firefox’s separate download manager window.
5. IIRC, Chrome’s “close-everything-without-moving-the-mouse” feature wasn’t in its earlier releases - and I had that functionality in Firefox (back when Firefox had a single close-current-tab button on the far-right instead of close buttons on each tab)
6. Who prints web-pages? Even in 2008.

But yeah, Chrome’s attempt at cutting down unnecessary UI was bold - and prompted Microsoft to redo IE9’s UI to look like Chrome’s in 2011 (despite that, they never fixed the “snappy” feel that Chrome has - why does IE still freeze briefly for 1-2 frames every time you switch tabs? Why is the address bar still so fiddly? Oh well, IE is dead now so we’ll never know...)
