I had the same problem as BigBadBassMan. Unfortunately I'm using ZendStudio so I can't update to Eclipse 3.6 until Zend does. My fix was to change tooltips to text=black and blackgorund=#808080, which is halfway between black and white. Now in both Zend Studio AND Firefox I can read the tooltips. To me it looks bad, but at least I can use it.
