Firefox 3 Doesn’t Render Nicely
For example, as the browser width decreases, the stuff the used to float and pop under in FF2 no longer does, and no horizontal scrollbars appear to help the user see what is cut off.
I don’t know whether to wait for the next release or spend a weekend trying to get my layout working.

It appeared this was caused by the now-uninstalled web developer add-on.
