I don't know what Bugsnaq is, and I probably will not ever know. Their site is #, so unless one allows some completely random site to run # ( # ) in your browser, you'll never see it.

Too bad, too! Their article on integrating # and # sounds like it would be very much worth reading. https://www.bugsnag.com/blog/tmux-and-vim ... until you remember the "unknown site wants to run JS" aspect.
