Though only really useful to those who can read code/program themselves, I find the "Extension Gallery and Web Store Inspector" extension to be useful for this kind of thing. It gives you an omnibar icon when you're viewing an extension in the Chrome Web Store/Extension gallery which let's you view the actual permissions the extension is requesting, a list of Chrome API calls it makes and you can also go in and view the actual code of the extension. I tend to do this before installing any extension. https://chrome.google.com/webstore/detail/bbamfloeabgknfklmgbpjcgofcokhpia https://chrome.google.com/webstore/detail/bbamfloeabgknfklmg...
