Well, I can see comments and my toolbar on LJ again. I uninstalled all the programs I didn't use on this computer, completely wiped Firefox, and started over. It seems to have done the trick. I am still unable to play Farmville, but I suspect that's because I updated Flash like it told me to, and this new update is crap. I'm hoping that in a few months, it'll update again and I can start playing FV.
Last spork chapter should be done within the next week. Fingers crossed!
