.caret in Firefox doesn't render correctly

Created by: gustavohenke

Hey, I've been trying Bootstrap for some days now. However, I've seen that the .caret element doesn't render well (actually, it looks VERY strange) in Firefox. I thought that was an known bug here, but couldn't find anything related to this in you GitHub repo.

Well, here we go, my setup:

• FF 14.0.1 on Windows 7
• Bootstrap v2.0.4

I've found this bug on Firefox's bugzilla. Maybe you should take a look. Using the CSS border-NullSideHere: 0 dotted; pointed by the bug opener seems to make it work fine.

Thanks in advance and sorry for bad english :)
