I don't think it's a serious issue, but it's annoying to keep seeing the crash report bar pop up in Firefox. Every time I visit this site, the QuickTime plugin crashes on every single page on the site. The site clearly has something causing QT to crash. You might look into it. It seems to appear only after the page loads, so it may be connected to the slow page loads.
I'm not sure how long this has been happening, but it's been happening a while now. I've just been ignoring it in favor of more important concerns.
