There’s not a single web browser out there that comes with all the features you could ever want, which is why extensions are such an awesome thing, but there is a downside to them. Whereas web browsers come from one group of developers that you know you can trust, extensions come from a variety of different developers from all over the world, and some of them like to gather information on you without you knowing. Fortunately, Chome users won’t have to worry about this in a few months, as Google is planning to require developers to notify users whenever their extensions collect data on them.
