Somebody suggested changing the internet settings and un-ticking the box that says: 'Show image download placeholders'... prob is, the box is already unchecked :enough!:
Personalise FF the way you want it, there are loads of things you can do to change literally every aspect of it. I was hesitant when downloading FF like you're hesitant now, but in the end, I now use FF; it's much better, and faster.
