Created attachment 576943 [details] firefox8-native.png User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.7; rv:8.0.1) Gecko/20100101 Firefox/8.0.1 Build ID: 20111120135848 Steps to reproduce: Implemented an HTML5 context menu Actual results: I got an HTML5 context menu. It's lacking some usability, though. Expected results: See attached image for side-by-side comparison. a) Firefox „simplifies“ the menu for images and links. Obviously I don‘t need „save image“ on a text-link, and no „reload page“ on either of them. Why do I get that stuff with html5 context menus? b) Add some checkbox/radio elements to <menuitem> of said types. Currently you can‘t tell them apart. c) Think about moving the Fx menu to a sub <menu> of the html5 menu. I‘d argue the html5 stuff is primary and Fx‘s „save image“ a secondary (yet still important and accessible) option.
There is some discussion about (c) on the W3C bugtracker where I just added a new proposal there which also kind of covers (a).  https://www.w3.org/Bugs/Public/show_bug.cgi?id=12999  https://www.w3.org/Bugs/Public/show_bug.cgi?id=12999#c22
… also, the last example for context menus in the spec shows a solution to (c) which "hides" the default/"native" context menu items behind a disclosure triangle (which is IMO the best solution, and is used on at least Windows and Mac natively).  http://www.whatwg.org/specs/web-apps/current-work/multipage/interactive-elements.html#context-menus
