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.
No longer works well Rated 2 out of 5 stars
while the app removes ads it, sadly, no longer enlarges the mail page and leaves the large empty block at the top.. Feb17
Needs Update (Revised) Rated 5 out of 5 stars
The stickiness problem has been resolved for now so I'm deleting my original comment and raising my Rating for the fast response. This is a great app and works removing both top and side blank spaces and filling out the mailbox.. Seems also to have survived disk and cookie cleaning which I thought may have caused my problem. Highly recommend the app.This review is for a previous version of the add-on (2.48).
