Yeah quite honestly stuffs like this make you look at security tools another way. Most of the time people just clear them off as either an overkill or just annoying popups but the fact that it saw something dangerous and did it before you did just makes a statement on its own. I too considered most of these browser add ons as a waste of space too but at the rate of people being caught out by links that are not what they really are you think it is rather clever to have a second pair of eyes keeping an eye on you. In particular, even a single mistake can be expensive to users who handle wallets and access random websites in search of airdrops. I have not tried Goplus yet but now I want to characterize it.
