removeAttribute doesn't seem to do so.
I am trying to do this in an <img id='player' src=' ' alt='alt' title='title' border='0' onerror="document.getElementById('player').removeAttribute('src');document.getElementById('player').removeAttribute('alt');document.getElementById('player').removeAttribute('title');" /> tag.
When I view Generated Source in FF2 (Web Developer 1.1.9), the attributes are not shown in the source listing, and the title attribute still displays in the page.
When I view Generated Source in FF4, the attributes are present in the source listing, and the title attribute still displays on the page.

(In my original post above, I had to use a space as the value for the src attribute, otherwise this editor would not show it. But my actual code is a zero-length string.)
I believe that FF4 does not consider a zero-length string as a triggerable error. I change the src attribute's value to '#' and all is working as desired.
