User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7b) Gecko/20040415 Firefox/0.8
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7b) Gecko/20040415 Firefox/0.8
When navigating form elements using tab/shift-tab keys it is impossible to
navigate past a form element that contains onfocus="this.blur()".
When an element that contains onfocus="this.blur()" is focused the focus is
returned to the previously focused element instead of advancing to the next
available element. This makes it impossible to navigate form elements using the
keyboard if one or more of the form elements contains onfocus="this.blur()".
Reproducible: Always
Steps to Reproduce:
1. Use the following HTML:
<html>
<head>
</head>
<body>
<form name="sample">
<select name="test">
<option value="1">One</option>
<option value="2">Two</option>
<option value="3">Three</option>
</select>
<textarea name="test2" onFocus="this.blur()"></textarea>
<input type="text" name="test3">
</form>
</body>
</html>
2. Attempt to navigate the form using the tab and/or shift-tab keys.
3. It is impossible to navigate past the textarea in either direction.
Actual Results:
If tabbing the focus returns to the previously focused form element and it is
impossible to advance past the element that contains the onfocus="this.blur()".
Expected Results:
When tabbing/shift-tabbing and a form element that contains
onfocus="this.blur()" is encountered the focus should advance past this element
to the next available element so that the form can be navigatted by keyboard.
It should be noted that in both Moz 1.6 and FireFox 0.8 (at least under XP)
tabbing to a form element that contains onfocus="this.blur()" causes a crash.
This has been fixed in recent nightly builds.

Confirming this bug on Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.8b4) Gecko/20050911 Debian/1.4.99+1.5beta1-2 Firefox/1.4 Occurs on a polish auction site Allegro.pl which is one of the most visited sites in Poland, making it impossible to navigate though it with Tab.
Still present in: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.8.1.3) Gecko/2007031002 Iceweasel/2.0.0.3 (Debian-2.0.0.3-2) Very annoying bug for accesibility. Why does it take over 3 years to fix this?
I made a Greasemonkey script to work around this bug: http://userscripts.org/scripts/show/9628
