Has worked perfectly for over two years always on Windows Home Pro 7 and newest version of firefox 64 bit.

At least, no longer the annoying adds!

Does what it says on the tin - no more of those irritating sponsored e-mails that float around Yahoo mail

well, that simple??? surely not. but, yes, it works.....why have i waited so long

useful addon when you still using yahoo mail

Made my Basic Yahoo Mail for Firefox free of Ads.

If you switched to the New Beta Yahoo Mail, then you have to suffer all the ads, so downgrade until the developer has made it work for the New Beta Yahoo Mail. I donated to show the love because with this add-on solves a problem when it is working.

I sometimes use the new Yahoo in Chrome and then use Webmail Ad Blocker, but that does not reclaim all the space from the ads. At least I am not drained by the ads while working.

I am desperate for Yahoo Mail Hide Ad Panel to work on the New Yahoo Mail!
Hurry Piyush!

This is an excellent add-on that performs exactly as promised. Its so good that I've actually forgotten what Yahoo Mail with advertisements looks like.
In addition to doing what its supposed to do, it is one of those rare things wherein the progression from values to motive to impact is logical and successful. Great Job.

Great for several years in concert with uBlock Origin, got everything including on 2017 beta. Yahoo beta is now permanent. I had to use uBlock on a top banner element, and a Yahoo video box shows over empty screens and has to be manually closed. Can't block it. I don't consider stupid videos a "bonus" in email, which is for email - full stop.

This add-on does exactly what it claims: Gets rid of the annoying Yahoo banner ads AND recovers the space they consume! Ad Block Plus also gets rid of the ads, but leaves huge chunks of white space. This add-on moves and/or expands the actual mail frame up and over to make full use of the screen. No configuration neccessary, so it's extremely simple to use. Just install it, and forget it. No Restart needed either, which is nice. If you use Yahoo mail, this is a must-have add-on.

Was working perfectly, so now has to be upgraded to work on the new Yahoo Mail Beta, as of Mar 31, 2017.

Thank you so much for developing this addon. Haven't had any problems with it so far, but there's been an obnoxious Turbotax ad coming up for me lately.

Would you be able to fix this please? I'm docking a star because of this issue, but I'll update my review with 5 if you can help me resolve this.

Edit: Haven't seen that ad in a while, so I guess it's working properly now. Bumping my score to 5 stars. :)

Works great on the current Yahoo Mail. However, I'm using the Beta version of the new Yahoo Mail and it doesn't really work on that. The right ad panel is sometimes hidden (but the space still shows) and sometimes isn't, while the top ad panel shows all the time. However, I would imagine that once the new version of Yahoo Mail goes wide, there will be an appropriate update to the add-on.

This app works great - Quick updates when Yahoo changes it's system.

Was having trouble getting uBlock Origin to hide the big ad blank space, this solved my troubles!
