About that, is there a clickable link to access the blocked site after the warning?. This is what I mean, you access a website and blocked by metamask and you want to access the site that is already proven by you that it's not phishing link or website and then you just have to click a link or button to access the site like continue to site or something like that. About the underlined "please file issue" does it take much time or not?
I think you should not go to this website with the browser installed metamask extension. Whatever the website is proven by you.
You can create a new profile chrome browser and go to the website what you want.
If you dont know how to create a new profile, I can show you.
