If someone asks for it, I might as well fix it. Updated bytingshark.user.js works (and is tested) with Firefox, Google Chrome and Opera. Safari is somehow experimental and I was lazy to do this, but hopefully it works :)
You will need to install Greasemonkey add-on. After that just open bytingshark.user.js and install it.
Just open bytingshark.user.js and it should prompt install wizard.
