No, you are not. I think there have been several over the years, here and elsewhere.
Perhaps this (rather recent) thread:
Screen capture over more than one screen in depth, with different software and links mentioned, is a good start.
(Several years ago I used the, then, free version (last one was v. 5.3, I think) of FastStone Capture to, eh, capture some pages. Later on changes in Fx meant that that version couldn't capture scrolling windows. Updates to FastStone Capture are often mentioned in
Other Applications.)
By the way, please call me if you find a good one.
