I am not a fan of these browser extensions at all. I do not want to use Metamask at all.
You have right to be not fan of it. Meta Mask is not safe because it is always open on Internet. It is a wallet direcly in your Bowser and it is always connect to your Internet. When you are visit a hack Internet site hackers will have direcly access to it because you are direcly on hack site from your Bowser where your Meta Mask is in.
