I broke Firefox

I have no idea what I did, but for some reason I can't get Firefox to
run. I tried to run it in the terminal and all it told me is that
allpears had connected and then the ternimal disapears. So I get to
play with my second favorite Web Browser, Konqueror. The only thing I
can't seem to do is log in to blogger so I'm doing this post from email.
w00t blogger for having a whole bunch of ways to post!!
