Did this just start happening? Did it happen in a previous version of Firefox? Is it happening in the latest nightly? nightly.mozilla.org
Fairly sure this issue has been around for a few versions of Firefox. I don't know exactly when it started, as it took me a while to consciously notice the issue and link it exclusively to Firefox.
