The eyedropper is using a panel with a call to openPopupAtScreen to open it (http://dxr.mozilla.org/mozilla-central/source/browser/devtoo...).

I'm not sure exactly in what ways this is failing, but please file a bug under "Developer Tools: Inspector" if you have STR and we can try to narrow it down: https://bugzilla.mozilla.org/enter_bug.cgi?product=Firefox.
