Last week, I entered a preliminary 2011 tax return into HR Block's site. I forgot which browser I had used on my main computer. I had thought it was I.E.
Today, I had to update it. I went in to IE, and I was immediately directed to Facebook. True, I'm usually logged in to Facebook on IE only. I don't want my taxes and personal finance accessible from Facebook (or Blogger, or Google Products, or anything else) so I disabled it, and then it appeared that my HR Block data had been wiped out.
I tried using Google Chrome (which, note, I recently had to re-install), and the stored tax data (for many years) came back, with no intervention from Facebook (because I'm not normally logged on to it through Chrome).
But this shouldn't happen.
