Well-known member
In latest Firefox (23.0.1), including default style on test 1.2.1 site and reproducible here at

Some buttons are not aligning properly...

One example of this overlay occurs when you try to add an image to a post in a thread.

It's even more noticeable if you don't use boxshadow or use custom styles.

This doesn't occur in Chrome at all.

I did try it and it may have resolved the issue, but it changes the button size fairly significantly so it's not something we would likely do in the short term.
