privacy

It was the first browser to have tabs.

Not true. I was definitely using tabs in Firefox and Opera before Chrome even existed. I've used CTRL/CMD+SHIFT+T to reopen last closed tab in all browsers for many years now so I can't remember if that existed as a menu option for people who prefer to use a mouse, but the guts of the feature itself was there before Chrome existed as well. (I avoid duplicating tabs so I can't say if that existed before.)

I remember clearly when Chrome came out, it felt like this stripped down skeleton with less built-in features than I was used to, less customizability, and less ~~features~~ privacy that promised to be "fast," yet didn't seem any faster than a fresh browser install would normally be. The one innovation I associate with Chrome is browser-based online and offline web apps, but I don't know if that started with them. (I'm guessing it probably did since they were in their heyday when that got to be a thing.)

I was so disappointed when Mozilla spent years trying to make Firefox more like Chrome (which meant stripping down features and customizability) to attract people-- which clearly wasn't working-- and it's been such a relief to see them get back to being simple on the surface but poweruser-friendly under the hood, recently.
