That website did not require disabling a popup blocker, but for other reasons I don’t recall, the website was unusable to me. So in the end I did not ask permission to use the road.
Note that #Mastodon’s webclient is dysfunctional to some extent with popup blockers. If you try to post an image and you want to add some alttext, the mechanism to add the text requires filling out a popup that’s broken if you block popups.
