GNOME Bugzilla – Bug 759036
extensions.gnome.org doesn't work under Wayland
Last modified: 2016-06-03 16:34:49 UTC
Running Fedora 23 under Gnome with Wayland.
We don't plan to support NPAPI plugins under Wayland.
There's nothing in the gnome shell npapi plugin specific to X11, I don't see why it can't work under wayland.
Works with WebKitGTK+ 2.12.
