That's not a reason to not use the browser though. If Chrome is superior except for one feature that can be fixed by an extension that takes 30 seconds to install once at the same time you install the browser, that's a really stupid reason to avoid the browser. Trying to add every single feature that every single person wants (and I don't consider this to be a necessary feature, especially considering there are better ways to switch tabs) just leads to a bloated browser, which Google wanted to avoid.
If you could buy a really great, affordable car, and the car's only downside was crummy factory tires, you buy the car and you put on some tires of your own choosing. You don't go buy a crappy car just because it has nice tires.
