What's there to trust in Chrome? Google not only gets to see everything you are doing that interests them in the browser but also refuses to allow full functionality and/or use of various extensions (depending on the extension) that are available in firefox. Besides, would you trust a browser by a corporation who tries to hinder those who seek to take control over their mobile devices, try to get spyware into everything and has their search engine programmed to allow them to decide what information you have access to on an individual basis to only let you know what they feel you should know?
