As far as I can tell there's no real point in using if you use Ublock origin instead of a lesser adblocker, but it definitively works.

It's working with blocking ads on Yahoo Mail now. Jason has fixed it for Yahoo Mail. Thank you Jason. Really appreciate it!

Used to be great, but it has now stopped working. Viewable area is no longer expanded to the right hand side.

Unfortunately, no longer works for Yahoo mail

At the time of this writing, the extension works perfectly for Outlook and does not work with Yahoo. It would also be nice if this was implemented for AOL since it is effectively the same as Yahoo. I would advise caution with any extension that can access what may be sensitive data depending upon your usage. Thanks to the developer.

works perfectly, must have add-on

Buenísimo ... al mneos con Outlook.com funciona al 100%
