Oh, that's a strange problem! I have an up-to-date firefox browser installed for just this sort of troubleshooting, but that issue isn't showing up for me at all. If you're using a skin for Dreamwidth, it could be interfering. If that's the case, we can edit this layout to work along with your skin. That's the first thing that occurs to me that could be causing this.

In the meantime, I put in some extra edits in the layout's code to try fixing the issue. It's hard to do without knowing what the problem is, of course, but I threw a couple of darts at the wall to see if something works. Let me know if that's improved it for you.

If you aren't using a skin and this issue is persisting, let me know and we'll try to find the problem.
