In Firefox, I was using a lovely extension which provided me the ability to do regular expression searches with the browser's built-in searching utility. Additionally, I had as of late been using Stylish, Socialite, and Ubiquity fairly regularly. In essence, I would love some sort of plug-in architecture aside from the very hack-ish input manager stuff we're currently limited to.
