Can't see Attached Thumbnails using Firefox

[RunningBum]

For some time now, I've been unable to see anything in a box with a title "Attached Thumbnails". Using a Win 8 PC with Firefox. When I use MS IE I see them, so it's not my forum settings. I recently installed Adblock and Ghostery but I feel sure I had this problem before then. I also use Noscript but I don't see any scripts I'm blocking that could cause this.

Any ideas what to try? Clearly this is a problem with me on Firefox, but I don't know what and I'm hoping someone else has seen this and solved it already. Thanks.

You may need to check your settings and make sure that ht tp://cdn.early-retirement.org/ is whitelisted (removed the space at ht tp). This is the url for our image storage you may have it blocked.
