260834 - Composing Yahoo Mail gives JavaScript errors

Status: RESOLVED DUPLICATE of bug 259935

(Core :: DOM: Core & HTML, defect)

Description

[Tim Powell]

Observed with Firefox 1.0PR on Windows XP:

When composing a message in Yahoo mail, I get a JavaScript warning about use of
document.all and then a steady stream of JavaScript errors "event is not
defined" for every key press. 

----
Warning: Non-standard document.all property was used. Use W3C standard
document.getElementById() instead.

This appears to be caused by the recent change in behavior of "untested"
document.all. I suspect that the code (condensed below) lets this.ie get set to
true:

	d=document;
	this.ns6=(this.dom&&navigator.appName=="Netscape");
	this.ie=(d.all);

This causes problems later:

function ylib_keyevent(evt)
{
	if(oBw.ie||oBw.op) evt=event;

document.all support may also be causing other problems with Yahoo Mail. See bug
260481.
