Suffice it to say, Google's been steamrolling through its services this week and laying down a variety of updates and goodies. Just a day after its short-lived Gmail iOS app was released, Mountain View's veered its wheels toward the "pluses" in its portfolio. To start, Chrome users will find two new extensions, including a +1 button and a Google+ Notifications box, to more easily mark their favorite sites, while those loyal to Internet Explorer can update their Google toolbar for a similar effect -- sadly, there's no such love for Firefox at the moment. Moving on to its social front, Google has finally enabled native YouTube support in Google+. While on G+, you'll notice a YouTube slider near the right, which when clicked pops up a video module (seen above). From it, you and your circles can quickly share your favorite viral videos and view playlists, which Google says are currently being added to G+ search results. Sure, we're still anxiously wishing for things like Twitter integration, but ya gotta start somewhere, right? You'll find a shot of those extensions below, and more details at the source link.
