What do the various parts in this screenshot indicate? This was taken when viewing an internal (org intranet) website login page via Firefox.)

I believe #1 in the upper right is supposed to be a count of the number of elements available vs those blocked (but I don't see any mention or reference to indicate where/how there are four blocked!)
#2 is bizarre (I know that is usually where the source domain is indicated)
#3 & #4 - what does it mean that they are checked but the surrounding areas is red?
I am trying to figure out why the interface for this website isn't working with NoScript enabled (even though I tried "temporarily allowing all" for the page.) It works in Chrome without NoScript
