If you're on OSX and not using the "default for display" resolution, that may be the cause of the issue. Don't have the bugzilla handy, but I stumbled across it at one point and confirmed that that was the culprit for me. Unfortunately, I'm unwilling to use default display res, so I'm hoping that gets fixed soon. Would love to standardize on Firefox for my every day browsing.
