Haven't tested this in other browsers yet but I was able to easily disable eHow's Spark in Firefox by simply adding the following to my web page javascript:

<script>window.sparkLoaded=true;</script>

Basically this tells it that eHow's Spark was already loaded so when you click on the button in the toolbar it refuses to load it, it's dead, defunct.

Just slap that line of code in your common javascript include file and eHow loses it's Spark site wide. Much easier than slapping meta tags in the top of all the pages and editing one lousy javascript include file, assuming you have one, disabled it site wide in a second.

This method could probably be used to stop any tool loaded in a toolbar without mucking up the meta tags. The only issue is it's not a supported method by the vendor so they can change that variable sparkLoaded to something else and it won't work, but it's an easy cat and mouse game to keep on top.

FWIW, that was much easier than my last frame buster script!
