As soos as I scroll down on this page http://www.familiealberda.nl/descend.php?personID=I331&tree=albtree1, the letters turn into white and make them almost invisible, whicht they should not (they have to stay blue). I had concact with the software builder but he did not experience that problem in Firefox. I use Firefox since I remember and I never had an issue like this. I switched off all addons and plugins but this did not solve the problem. However only starting in the safe mode solves it and leaves the letters in the original color. Renewing Firefox or reinstalling it (after removing all the leftovers in hidden folders Appdata an Program data and removing registry settings) does not solve it. Only restarting in the safe mode. I can't figure out how to solve me, which made me switch to another browser where I don't encounter this problem.. Anyone?
