MacBook Pro Mavericks 10.9.5 Firefox 36.0.4 No problems before this release. I've seen a lot of traffic on your site about this issue, but didn't seem to find a satisfactory solution. None of the remedies presented fix the issue. Seems like this has been a bug for awhile, but I've never experienced it with previous releases. Please fix this ASAP. A web browser is useless if I have to go over to the scroll bar all of the time.
