If you want to install Chrome extensions, Google's Chrome Web Store soon will be the only place to get them.

Extensions -- the software that lets you do things like block ads, manage your tabs better, explore art on your new-tab page or cover your screen with doge dogs -- can be useful and fun. Unfortunately, they can also be a conduit for malware that spies on you or cryptocurrency miners that let others profit off your computer's horsepower.
