How to permanently hide elements of any web page from Firefox
First thing you need to do is install the extension. That's a bit trickier than you'd think, because the latest version isn't yet compatible with Firefox 3.01. Fortunately, you can force it to work by preventing your browser from checking for extension compatibility.
Once the plugin is up and running, you can right click on any portion of any web page and either remove that section permanently, or click the RIP advanced button for additional options. Keep in mind that if you remove an element, it will only be gone from a single URL. For example, if you remove the Download Squad logo from our main page, it will still show up on article pages, search pages, and so on.
It's also worth nothing that your browser still downloads the files. You just won't see them. So Remove it Permanently won't reduce your bandwidth use, it will just make obnoxious web sites like MySpace slightly more bearable to read.
