Don't worry! I've been using it all today and so far it's had none of the bad effects you describe whatsoever. I plan to continue using it. It does actually let through ads uBO doesn't (though it embeds uBO and uses the same filter lists), but nothing I can't live with. Doing my bit to make Internet advertisers' lives that little bit more miserable is pretty much an ethical obligation at this stage. The FAQ does say only to run it if you know what you're doing. But I think anyone who reads HN will have no problems whatsoever in running this extension. If they do, the code's right there.
