Apr-11-25, ff v137.0.1, win10.
Today, yahoo attacked my mail with "violating terms of service" for using ublockorigin. Tried this add-on and it seems to work as advertised!

rotten service cannot access mail, by yahoos blocking

not working anymore. Uninstalling.

This add-on is outdated! Search for "Yahoo! Wider Mail" for an alternative add-on.

Doesn't work as of 1/24/2025. I have a new Yahoo mail account and added this plug in to ,my Mozilla Desktop - Windows 11 and it does nothing.

Doesn't work as of 1/15/2025

It was good until a few days ago, now get banner ads on top in certain emails .. Please see if you can fix this .. Yahoo wants us to use Yahoo Mail Plus for $5 per month ... Thanks

It doesn't work, I'm using firefox 120.0.1

REVISED: It didn't hide the Ads panel on the right side of New Yahoo! Mail for a while in Firefox 118.0.1. Now in Firefox 119 everything works again as expected

stop working here too...... :(

Has worked well for me for years....but just recently the (empty) ad panel has reappeared, and the Inbox command line disappeared. 8/23

This add-on works great for removing ad panels on the side, however, at the top of the preview window it still shows the "Deal Summaries" & website logo & link...if this gets fixed I will update my review to 5 stars & recommend more...thanks

No longer works.

App no longer works. Tried to contact developer but no response.

Was working great but now the yahoo email ad panel is back with ads. Maybe needs a new update.

Seems to work a stated.

It was great not having the right side of my screen taken up by blinking ads and the entire width showed the email name. Then a few days ago it changed. Now on July 10 I just have a rectangle that reduces the email name again. The rectangle lists Yahoo Mail tools and the Firefox Add-ons Manager says "Can't read and change data on this site."

This is my 12.12.21 review update for those who've commented about the Contacts and Calendar panels being blank when you click the icons. A workaround is to launch the gear icon mail settings, click "More settings" and then click "<— Back to Inbox". The Contacts and Calendar panels should show up now when their icons are clicked. Works for attachment previews too.

As me2 wrote three months ago:
"This addon (v3.60) breaks some features of yahoo mail.
When I click on contacts or calendar icons, the panel opens but it is completely blank.
The same happens if i try to preview an attachment (images, docs, etc)."

Up until FF upgraded 93.0 (64-bit) with both Win-10 & 7 (on PC), this has been a 5-star rating. It actually still is. Grateful and thankful for the author's work on this.
Currently I would consider this a broken app, because yahoo has found a way to push their right side ads again. The screen is being occupied by their garbage again.
They have also been able to temporarily push their small ad area above the subject lines (shows up for a few seconds, then goes away).
This has been an exemplary program. I am hoping that the author can find a way to smack down yahoo again.
