Martin,
You would have to create an add-in for the respective browsers and then
manipulate the Document Object Model (DOM) from within the add-in to change
the elements on the page. For Internet Explorer, you want to use a Browser
Helper Object. I'm sure FireFox has an add-in model, but I am not sure what
it is (it should be easy to find).
