Now I've got you

I'm having an interesting problem with Firefox 3: I'm unable to close my blog. Once I go to my main blog page, I can't close the tab or navigate away from the page, or Firefox segfaults. I like to hope all my readers have this problem, because then it's like a feature of my blog, but I expect not. I tried disabling Flash and all my extensions to no avail; I suspect the problem is one of the other media plugins, like Totem for playing audio clips. On the rare chance that somebody else is having this problem, let me know
