I was using firefox-78.0-1.fc33.x86_64 on Wayland in Fedora Rawhide in Plasma 5.19.2. I opened Help > Troubleshooting information and closed it. I clicked on the Bookmarks menu. Firefox crashed with a segmentation fault in wl_proxy_marshal_array_constructor_versioned at src/wayland-client.c:734 in libwayland-client-1.18.0-1.fc33.x86_64 which was
message = &proxy->object.interface->methods[opcode];
The crash address was 0x10 which might indicate an invalid pointer such as proxy.
