I use the noscript firefox extension, which blocks javascript from sites where I haven't told it to accept, and notifies me when it's doing so. I just opened one of my own LJ posts (with no comments or links, save a couple of <lj-user> tags), and noscript told me a javascript from "bidz.com" was trying to load on the page. WTF? Who is bidz.com and what is their javascript doing in my LJ?
