Why might loading to http address indicate a missing item and any ideas what might be missing?

Question

For days now, the http loading bar indication at the base of my browser window always indicates one missing item.
For example, for this Yahoo question page, it shows "http://answers.yahoo.com/question/... ..., completed 80 of 81 items."
I'd appreciate any input as to what may be causing every destination to be 1 short of completion; and what could be the mysterious, missing item??

Gregory_Dittman, no added spyware and no blocks, no change in cookies; am thinking about it; feels like a firewall deficiency, because of subtle seemingly unrelated peculiarities. Your input helps.

not true; if it is part of the program, it likely works with the whole. If it is a security item, it could be more important than many. There is no way for one to know if it is important without knowing which item.

Answer 1

A cookie, spyware etc. If you blocked them, they won't load.

Answer 2

Clearly, nothing important.
