We've seen this before on at least one other website, but I'm not sure where the original bug reports is. 1422700 1 cadubentzen 2018-05-10 06:05:30 -0700 I can reproduce it every time with Epiphany TP, but not once with MiniBrowser in Debug or Release mode. This is odd. 1422713 2 mcatanzaro 2018-05-10 07:28:03 -0700 Interesting, you're right that it doesn't happen in MiniBrowser, even with the Tech Preview versions of everything. Test: $ flatpak run --devel --command=/bin/bash org.gnome.Epiphany $ /usr/libexec/webkit2gtk-4.0/MiniBrowser MiniBrowser handles it fine even with some tabs created. 1422715 3 mcatanzaro 2018-05-10 07:39:06 -0700 It's caused by Epiphany's adblocker. 1425438 4 mcatanzaro 2018-05-19 09:49:26 -0700 It's caused by the Fanboy Annoyance List, https://bugzilla.gnome.org/show_bug.cgi?id=796245
