Here's a hint Rated 3 out of 5 stars

Update to previous review, I noticed that if I disable adblock plus yahoo mail will first open with an ad at the top of the page. However after I open an email title the new page enlarges w/o the blank space. There's a disconnect between AdBlock and this add-on but there's a workaround.
