Example: in Facebook, the search bar has a grey text "Search for people, places and things". Usually, when I click it, the cursor will blink to the search bar and the grey text disappears. But what happens to me is that when I click it, the cursor will blink to the search bar, but the grey text "Search for people, places and things" is still there... It will only disappear if I type something, but deleting the words I typed will let it reappear. I was just wondering why is this happening... Because I don't know if this is normal. Is this a new feature of Firefox? Because I recently just updated to Firefox 15.0
