Things look weird for me too. The comment box is really short and in the wrong place and I can't see the vertical line that indicates a quote in comments. I just went up to Firefox 5, so I was assuming the problem was on my end, but now I'm not so sure.
That's interesting. I'm on Firefox 8, which is highly beta, and I have no issues. I would expect a more beta version of the same browser to have more issues, not fewer.
I can't see the comments under posts anymore. This just started happening in the last day or so. (If I know a comment is there, I can still see it in the "recent comments" section.) I'm using IE8 at work (CORRECTION: IE7), where a lot of stuff is blocked for security reasons, but not in a way that kept me from seeing comments until recently.
What changes were recently made to the site that would cause this? It would be really nice to undo those.
Btw, I won't be able to see the replies to this post unless I find them under "recent comments", so ... if you want more specifics about how it looks on my end, you'll probably have to PM me.
