I could not register on WineHq just now.
https://forum.winehq.org/ucp.php?mode=register
The Remember Password pop-up kept popping up and disrupting the registration. There were 2 problems:
1) It kept insisting that my email address was my chosen ID for WineHq. That's minor.
2) It disrupted the process. I don't mean personal annoyance.
The last step of the WineHq registration page is a security question. When I answer it and press Submit, the pop-up causes the page to erase my answer.
After several attempts I used the drop down box to select Not Now. But Firefox doesn't understand that "Not Now" should mean "Not now on this page" and stop popping up on that page at least for the session.
After a couple more failed attempts I selected Never. That's not what I wanted but I could fix it later. In effect I was using Never to do what Not Now should do.
But by that time WineHq decided I was a bot.

BTW, this very page has an acknowledgement that I have logged on but when I select Preview or Submit it erases my message and demands that I log on again.
I only got it to work if I checked the "Log me in automatically" box. Fix that, too.
