Also note: Installing extensions manually can be dangerous! When you don't install from a store with lots of good reviews, it is harder to tell you are installing the software you intend to. Only install manually as a last resort. This kind of installation is much more prone to phishing, so make sure you are getting your MetaMask release from a trustworthy (official) source!
