Yep, either you do this on preference change which is probably easier
than going through all windows. I would rather hide those though,
instead of removing them.
You could also check on every menupopup if your items should be
displayed at all.
The following is for the contentContextMenu, but your should work similar:
var context=document.getElementById("contentAreaContextMenu");
if(context) {
context.addEventListener("popupshowing", function(event) {
rdr.contextMenuCheck(event); }, false);
context.addEventListener("popuphiding", function(event) {
rdr.contextMenuClean(event); }, false);
}
In the contextMenuCheck you should discard all events coming from
other contextmenus:
if(event.target.getAttribute('id')!='contentAreaContextMenu') return;
and then you can simply check for whatever you need and then finally set
document.getElementById(id).hidden=true|false;
Hope that helps.
