Currently, the Indiana state government website has a number of high profile pages which feature a prominent thumbnail image of the current Governor, which points to the homepage for the Governor's web content. It sits atop a retractable footer element, but the thumbnail itself does not retract when a visitor opts to hide the footer. The page's underlying markup refers to the thumbnail as a "CTA", which stands for "call-to-action". This is marketing speak for the part of a webpage that is supposed to encourage the visitor to engage in some desired action.
As a citizen wishing to find useful information on my state's website, I found the idea of aggressively promoting the Governor on the front pages to be obnoxious, if not ethically questionable from the standpoint of using state resources to promote a specific politician. As a software developer, I knew there was a way to script the suppression of this content. That's why I developed this Firefox extension. All it does is seek out the HTML markup and hide it from view.
Right now the thumbnail is still seen briefly on page load. As I become better versed in the extension APIs, I may refine this code or even augment it with customizable effects. This code is distributed under the MIT license, as it depends on jQuery to do its magic. Feel free to repurpose as needed. Try to use it for good. :-)
