so which is better dragon or chrome cuz they both look same ! ???
Both are based off of the Chromium source code.
There are changes between the two, but the ones that I consider most important concern privacy. Google Chrome contains a lot of mechanisms which can track you, in one way or another. Whether that is a concern to you or not is up to you. Comodo Dragon has removed those problems, and added some security enhancements.
If you have any more questions feel free to ask.
ohh i forget about flash , so hows flash on dragon ?
Works fine here. I’m writing this in Dragon.
