This applies only to Windows XP SP3 as far as I can tell, but I suspect may affect a fair number of users. Basically, my custom mail program uses a textbox for the subject line so you can rename messages based on their content, displayed as a PDF attachment in an iframe. Only in 3.6 does this happen, it was fine in 3.58 and all FF versions prior. The arrow keys, as well as Home and End, are inoperative in the textbox but appear to control the Adobe reader, scrolling the document etc., even when the textbox has focus as noted by a blinking caret. This breaks my app because I am depending on the dropdown automatic selections to rapidly classify messages, a la Amazon's Mechanical Turk. Please fix in next update, I'm sure this has something to do with the key event filter chain.
Reproducible: Always
Steps to Reproduce:
1. Go to http://xenoscience.com/mozilla/problem.htm
2. Note that arrow keys do not move caret in textbox
3. Note that Home and End are also disabled.
Actual Results:
arrow keys do not move caret in textbox
Expected Results:
arrow keys should move caret in textbox
This does not happen on Linux versions of Firefox, by the way, but my Ubuntu installation is 3.58.

Severity: normal → major
I am seeing the same problem on Vista SP2 using Firefox 3.6.3. I confirmed that this problem did not exist on 3.0 and 3.5. Something is swallowing the keydown and keypress events. I have a testcase that can be used to easily show this.
---BEGIN TEST
<html>
<head>
<title>JavaScript - Detecting keystrokes</title>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
<script type="text/javascript">
var pdfURL = 'http://samplepdf.com/sample.pdf';
window.onload = function () {
init();
};
document.defaultAction = true;
function init() {
var x = document.getElementById('testForm').getElementsByTagName('input');
for (var i=0;i<x.length;i++) {
x[i].onclick = setEvents;
if (x[i].checked)
x[i].onclick();
}
writeroot = document.getElementById('writeroot');
document.getElementById('emptyWriteroot').onclick = function () {
writeroot.innerHTML = '';
return false;
}
}
function setEvents() {
if (this.id == 'default') {
document.defaultAction = !this.checked;
return;
}
var eventHandler = (this.checked) ? detectEvent : empty;
document.getElementById('textfield')['on'+this.id] = eventHandler;
//document['on'+this.id] = eventHandler;
}
function detectEvent(e) {
var evt = e || window.event;
writeData('<b>'+evt.type+'</b>: keyCode=' + evt.keyCode+' : charCode=' + evt.charCode);
return document.defaultAction;
}
function empty() {
// nothing
}
var writeroot;
function writeData(msg) {
writeroot.innerHTML += msg + '<br />';
}
</script>
<style type="text/css">
body {
font-size: 12px;
}
#writeroot {
height: 300px;
overflow: auto;
border: 1px solid #2EB2DC;
}
</style>
</head>
<body>
<form id="testForm">
<input type="checkbox" id="keydown" /> <label for="keydown">keydown</label><br />
<input type="checkbox" id="keypress" /> <label for="keypress">keypress</label><br />
<input type="checkbox" id="keyup" /> <label for="keyup">keyup</label><br />
<input type="checkbox" id="default" /> <label for="default">Suppress default action</label><br />
<input type="text" id="textfield" /><br />
<button id="emptyWriteroot">Remove messages</button>
</form>
<a href="#" onclick="document.getElementById('docviewer-page').src=pdfURL;return false">Now load IFrame</a>
<p id="writeroot"></p>
<div id="container2" style="border:1px solid black;width:400px;height:200px">
<iframe
id='docviewer-page'
name='docviewer-page'
title='document page'
src='http://www.google.com'
align='left'
width='100%'
height='100%'
scrolling='auto'
frameborder=0></iframe>
</div>
</body>
</html>
---BEGIN TEST
Paste the above into an HTML document. Open the HTML document in firefox. Check the four checkboxes. Move into the text field and press arrow keys and enter key to observe the results when it is working correctly. Then click on the "Now Load PDF" link. Press the arrow keys and enter key again and observe that the behavior has changed.
This is a major problem for my application.

I have the same problem here and it breaks my XULRunner based application.
Looks like bug 556820 handles the same problem.

The testcase shows the behaviour. After loading the pdf dynamically in the iframe the caret is still blinking in the input element. But when typing no character will be entered.

Safari seems to have the same bug (Windows 7). In IE and Opera the input element looses the focus.

This is still a problem in 3.6.8, I'm trying to see if it's specific to Adobe Reader as I've installed Foxit Reader for Windows XP.

Wanted for the 3.6.x branch, but not blocking security updates. Will look at a patch if it gets a trunk fix.

I notice that Acrobat is stealing keystrokes even when another part of the UI
is focused. For example, while the testcase is loaded, click in the url bar and
start typing. Then press cursor up/down. The pdf page scrolls even though focus
isn't in it.
Bug 521951 may also play a role.

Is this an issue for 1.9.2 only, or does it apply to trunk as well (i.e. Firefox 4 beta6 etc)?

I observed a similar behavior today in Firefox 3.6.13, running on Windows 7 Ultimate. The PDF is in a standard frame, rather than an iFrame, on the page where I encountered this issue.
Holding the arrow keys long enough to trigger auto-repeat successfully moves the insertion point. Home, End, and single presses of the left or right arrow keys are ignored.

I'm still seeing the issue. Not just in iframes, but any time the plugin is in use. Out-of-process plugins are disabled on my computer.

I have this issue with XUL Runner 19.0 under Windows 7.
Have tried Adobe Reader X & XI both versions behave in the same way.

For anybody else that runs into this problem I worked around it by loading the PDF using http://pdfobject.com/ in an HTML iframe - rather than loading the PDF directly into the iframe.
