Hi, I recently upgraded to firefox 13. In the preferenced I had set "When firefox starts" to "about:blank" and "Home Page" to "about:blank". This had worked for several versions.
Now -- after visiting a site -- a thumbnail of that site is shown on the "blank" page now. I had looked through my addons, what may be guilty for that and found nothing. How can I get back a really blank page again? Thank you very much in advance! Best regards, mcc
