Mozilla Frefox

I started using Mozilla Firefox and I realy like it. The only problem is, when I'm logged on to this site it will not let me see the entire response in the thread. It seems to happen when someone uses the quote function as part of their response, it is just a big blank.

Has anyone else ran into this problem?

I really liked Firefox initially but gave up after it did that on a couple of sites I frequent.
Using Safari now - works fine (I have a Mac)

I started to run mozilla about a week ago and all i noticed is that the margins are bigger,No missing posts

I've never seen it and I've been using Firefox for about a year on this site.
I'm currently using version 1.5
