Please upgrade gtk3 to at least version 3.24.3. The current version of gtk3 in Fedora 29 (gtk3-3.24.1-2.fc29.x86_64) has a major bug when using Select All (CTRL+a) in Firefox with Wayland. Fedora Rawhide already has the fix. Firefox with Wayland crash on wl_abort() when selecting more than 4000 characters in a <textarea>: https://bugzilla.mozilla.org/show_bug.cgi?id=1539773 On Wayland, notify_surrounding_text() crash on wl_abort() if text is longer than 4000 bytes: https://gitlab.gnome.org/GNOME/gtk/issues/1783
I created a PR to update gtk3 to 3.24.7 in Fedora 29: https://src.fedoraproject.org/rpms/gtk3/pull-request/4 I'm not sure if it's the proper workflow.
