Review for Dragon:
This browser google chrome-like appearance, because his engine use chromium. In terms of security, the browser really is very protective of the sites certificate not clear, even facebook was considered dangerous, because he’s just ssl registered in the name of the site only, not individuals. In terms of performance, the same like google chrome.
Shortcomings, this browser does not support extensions like google chrome. In addition, thought he can use google chrome theme, but the results is not perfect, because several different interface of google chrome.
