In case anyone else is highly annoyed by the "lightbox" image popups, making a Greasemonkey script with this code...
if (typeof window.addEventListener != 'undefined') window.addEventListener('load', onLoad, true);
function onLoad() { window.setTimeout("delete YAHOO.util;", 1); }
...should get rid of the boxes. I haven't yet noticed any side effects, though I cannot guarantee that there aren't any. I know that middle-clicking achieves the same damn thing, but I've fallen into the popup box trap often enough now :irked:
Alternatively, you can also use AdBlockPlus (or any similar extension) and add a filter like this: *lfsforum.net/*yahoo-dom-event.js*
However, this has the drawback that all other dynamic popup functionality (clicking on a username, etc.) gets disabled, too.
E: Corrected code, previous code made multiquote (and possibly other things too) not work.
