After the latest update, Fireshot is excellent for capturing an entire web-page.

Fast, rapid, and allows configuration when saving after the photos are taken.

One issue before the update, was big pages would not capture completely.

I have yet to take a massive page shot since, but it seems that they split photos up, preventing this issue.

Nonetheless, your at a great loss if you do not atleast try Fireshot out. It works excellently.
