HTMLElement.prototype ... workarround

in Konqueror-3.5.3 I get

Line 532: {HTMLElement.prototype.removeNode=....
hmm ... we know that HTMLElement prototyping doesn't work out of the box in KTHML-based Browsers - so it seems like they didn't even test their stuff in Safari!

But we are lucky - there is a simple workarround:

Ajax problems are manly caused by small javascript-cross-browser-differences. But there are well done libraries like http://www.mochikit.com to fix this.

Of course it didn't work --- it's non-standard behavior that's basically an implementation detail of Gecko! Comparable code for Konqueror would be to use
window["[[Element.prototype]]"]. Unfortunately typical "Web 2.0" webmasters seem to think that IE and Mozilla are the only browsers, forcing other browsers to emulate things like this, and also non-standard language extensions like getters/setters (typical pattern seems to be to use Mozilla extensions to emulate IE extensionw). This does, BTW work in upcoming 3.5.4 to some extent (just for the base classes, KHTML doesn't have separate prototypes for divs and such); and to a fuller extent in development version of Safari.
