*** Plugin should call <tt>NPN_GiveUpFocus</tt> in response to the tab event, browser should return <tt>true</tt> and then call <tt>NPP_GotFocus</tt> with <tt>NPFocusNext</tt> for the direction argument to return focus to the first element in the plugin. If the browser does not want focus to wrap around then it can return <tt>false</tt> for the <tt>NPN_GiveUpFocus</tt> call. Plugin does not pass the tab event to the browser either way.

Mozilla bugs [https://bugzilla.mozilla.org/show_bug.cgi?id=78414 78414] and [https://bugzilla.mozilla.org/show_bug.cgi?id=93149 93149] have some information but are generally cluttered with useless comments. Deneb Meketa from Adobe posted a proposal on [https://bugzilla.mozilla.org/show_bug.cgi?id=93149 bug 93149], comments [https://bugzilla.mozilla.org/show_bug.cgi?id=93149#c34 #34] and [https://bugzilla.mozilla.org/show_bug.cgi?id=93149#c36 #36] discuss it.
 
There was a [https://mail.mozilla.org/private/plugin-futures/2004-March/000057.html plugin-futures discussion started by Johnny Stenback in March of 2004] on the topic of handled status for key events. Johnny's discussion resulted in a [https://intranet.mozilla.org/PluginFutures/index.php/PluginEvents plugin-futures wiki entry].
 
Aaron Leventhal of IBM started a [https://mail.mozilla.org/private/plugin-futures/2004-April/000064.html relevant discussion on plugin-futures in April of 2004]. The proposal discussed is an extension of Johnny's from March of 2004 and is actually fairly detailed.
 
API modification work is discussed in [https://bugzilla.mozilla.org/show_bug.cgi?id=348279 Mozilla bug 348279]. The discussion there generally revolves around a proposal from Sun. Sun posted to plugin-futures about this work in March of 2007.
 
Karl Tomlinson [http://groups.google.com/group/mozilla.dev.tech.plugins/browse_thread/thread/7b21b6b08499941d/5458da943ed1a81b#5458da943ed1a81b wrote a message on Google Groups proposing an X11 windowless plugin API]. There is some related info in that message.
