firefox add-on shortcut does not work anymore - firefox

Question

I have used following commands in my browser.xul to set a shortcut for my addon.
<keyset id="mainKeyset">
<key id="key_convert"
modifiers="accel"
keycode="VK_F12"
oncommand="myfunction()" />"
</keyset>
It used to work for previous versions of Firefox, but not anymore for newer versions.
has anything changed in the syntax?
Thanks

Answer 1

That code example looks correct, I suspect that there is some code within myfunction() that is failing, so we need more information probably. Try to replace myfunction() with alert("test"), that should work.

Some notes:
You must add it to a keyset, as the key listeners are attached when keyset is added

You must set an oncommand attribute

Can copy paste this to scratchpad:
var keyset = document.createElementNS('http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul', 'keyset'); //http://forums.mozillazine.org/viewtopic.php?f=19&t=2711165&p=12885299&hilit=mainKeyset#p12885299
//cant use mainKeyset see topic above
var key = document.createElementNS('http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul', 'key');
var props = {
id: 'key_convert',
modifiers: 'accel',
keycode: 'VK_F12',
oncommand: 'alert("tirggered")'
};
for (var p in props) {
key.setAttribute(p, props[p]);
}
keyset.appendChild(key);
Services.wm.getMostRecentWindow('navigator:browser').document.documentElement.appendChild(keyset);
