Google+ is breaking every growth record out there, in its first month or so it's been growing unlike any other website out there. comScore estimates that there were 25 million visitors to the site in the first month it was live and the number is continuing to rise.

But there was an even more interesting metric in the comScore numbers, most of Google+'s visitors are Google Chrome users. In fact, the regular rankings in the browser market are flipped on their head.

Google Chrome is the top browser, followed by Firefox and only then by Internet Explorer.

Granted, Google+ has been very popular with early adopters, which are likely to use alternative browsers and not IE. Still, the numbers are impressive.

A full 59 percent of Google+ visitors, which is not the same as registered users, were running Google Chrome, in the first three weeks after launch.

ComScore is referring to browser penetration here, which registers whether a user visits the site with a particular browser or not. One user could visit a site with different browsers in the same time period, which is why the percentage numbers add up to more than 100 percent.

Firefox only had 25 percent penetration, while Internet Explorer had a paltry 23 percent. This compares to 31 percent browser penetration for Chrome on the web as a whole, in the US, 32 percent for Firefox and 87 percent for Internet Explorer.

Clearly, Google+ users love Google Chrome. It is interesting though that they chose this browser in particular to visit the site, the fact that it had Google in the name very likely had something to do with it.

Of course, Google+ works very well (and the same) in Chrome as it does in Firefox and in Internet Explorer, but the benefits of a powerful brand, in affecting behavior, are clear in this case.
