Lately, I've been noticing that any search I do in Yahoo! produces a popup alert error that says, "Internal Error: result.childNodes.childNodes has no properties". For a while now, I assumed it was a Yahoo problem, but it looks like I was wrong about that. Searching for that error seems to indicate it is a result of the SEO for Firefox addon from Aaron's SEObook tools. I'm not sure that's true because disabling it didn't seem to solve the problem, but maybe I have to reboot or something. Anyone out there know anything about this one? I'm getting tired of the stupid error message popping up.
