Why do people always say this as the reason for why they use a particular browser?
They're ALL blazingly fast. I'm not going for a coffee break to load a page.
It is the default choice nowadays. Most people on the Internet are not emotionally invested in whose browser they are using. They just want to use a browser that works on every site.
Unless you’re using Internet Explorer, every browser works on every site. I’ve never had Chrome installed even as a backup. Have yet to find a site that doesn’t work on Firefox.
The thing that makes chrome completely unusable to me is how you can't Ctrl-Tab between tabs in recently-used order.
Maybe it's possible to do it with an add-on but I don't like installing add-ons because they always want access to your complete browsing history. I'm not doing that just to restore basic functionality.
Whatever Google may wish, Chrome is not the internet. And given the choice, it is reasonable for a person to question why anyone would choose Chrome. I mean, I think there are plausible reasons[0], but it's an understandable view.
