--- Comment #3 from Carl Austin Bennett <carlb...@hotmail.com> --- It looks like this odd behaviour is caused by Greasedlightbox, a Firefox extension which pops up an image viewer which looks very much like the MultimediaViewer but is not. That browser extension is either incompatible with MediaWiki or with MultimediaViewer, remove it and the issues go away. -- You are receiving this mail because: You are the assignee for the bug.
