Fine on FireFox 2.0.0.16/WinXP. Which Firefox are you using? If you're on 3.0 make sure you upgrade to 3.01 as it's a lot more stable.
Good call, I upgraded from 3.0 to 3.01 on Leopard. And it doesn't crash anymore, though it doesn't crash Safari either anymore, so I'm thinking it could have been something on their end that's since been updated.
plz let me know if it does - i think at one point there were so many comments going in at the same time that funny stuff was happening with wordpress
