I'm using epiphany 3.31.2-11-g474e55d7 with WebKitGtk+ 2.22.3 from gnome-nightly's flatpak, although it has been happening already for some previous versions. When accessing some specific URLs, ephy freezes. I cannot close tabs, close the whole session or continue browsing. This is not the actual problem reported here. It is being tracked at: https://gitlab.gnome.org/GNOME/glib-networking/issues/46 The problem is that, using Ctrl+Q doesn't work. It half closes the session, though, leaving only opened the first window opened and the window in which the frozen tab has happened. This shouldn't happen since webkit_web_view_close() ought to work even when network process is hung. This URL might show this behavior: https://incomplete-chain.badssl.com/

OK, turns out that it's no problem to close the tab that triggers this deadlock, or any tab created before the deadlock is trigger. It's only tabs created afterwards that are not closeable. That's because Epiphany tries to run code in the web process during the tab close (Ephy.hasModifiedForms). That's probably the best we can do in the event of deadlock, so let's move this back to Epiphany to find a workaround there.
