Maximum PC: If you’ve ever downloaded a free app to use on your PC, it’s probably happened to you. The installation goes great, the program works as advertised (or doesn’t), but it isn’t until you open a browser window that the true cost of using that free app is realized. Freeware tools love to install obnoxious tool bars, search engine replacements, and the most insidious ones install extensions with missions completely unknown to the user. For applications like Skype this can add useful functionality such as click to dial, but more often than not, silently installed extensions do more harm than good. That’s why we were ecstatic to learn that Google is finally tackling the problem head on with Chrome 25, and will hopefully inspire the other major browser makers to take action as well.
