Talk:UnsafeWindow

We should add an example of an exploit. If not running code (would be nice) for security-by-obscurity reasons, then at least explain what could happen. --195.67.240.29 17:39, 13 April 2007 (EDT)

How to do I use GM_setValue safely?

I want to insert in the page an HTML element that can be used to update a preference.

My strategy for doing this is:

• add the element in the userScript, with an onclick property set to call updatePref(new_state);
• add a function to update the setting to unsafeWindow, here is the function:

	unsafeWindow.updatePref = function(state) {
		var s;
		if (state) { s = true; } else { s = false; }
		GM_setValue('pref', s);
	};

Questions:

• Is it safe?
• Is there a better way that does not involve unsafeWindow?

You should be able to just define the method on window. So try just

function updatePref(state) {
  …
}
