The green box that pops up about the new enhanced HTML article does not have a "close" function. It blocks the article I'm trying to read.

Problem for me as well.
This happens to me on Firefox 42/Mac 10.10.5
I want to add to this. Make this box easy to close with a big 'ol "X" in the corner!!
This happened for me too.

The "You are viewing our new enhanced HTML article." message blocks a part of the article/abstract.
