Greasy Fork

Sign In with Greasy Fork - doesn't work, just erases history

1. I open this link https://greasyfork.org/en/forum/discussion/11144/add-pixsense-net
2. I click "Sign In with Greasy Fork"
3. it takes me to https://greasyfork.org/en page with yellow text "登录成功" and erases the previous page I was on from history with no way to go back there
4. So I open email again to find that link, go to it again and I see "please log in" again... I'm not logged in

I'm not sure about given part, it happens after I don't visit this website for long time and all cookies expire I suppose when I open email link
