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

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."

As me2 wrote three months ago:
"This addon (v3.60) breaks some features of yahoo mail.

The same happens if i try to preview an attachment (images, docs, etc)."

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).

Unfortunately, it breaks core functionalities of yahoo mail.
I think this extension is too aggressive!
Indeed, it does hide the panel at the right, but however,
this panel is used also to show contacts, calendar and
previews.
After installing this extension, the right panel is always
blank when you open it, regardless of the content it should
display, not only ads!
This means you can't see your contacts or your calendar and
also, you can't preview an image or document from email
attachments.

Well, the addon did not work for me, I am using version 66, installed with no issue but made no change at all to that annoying ad that is placed at the top of the email inbox page......we missing something??

It was working until I accidently hit Control 0 and then it leaves a large blank space on the right side as opposed to the smaller space it used to leave. My other computer with this ad on still has the smaller space on the right side. I removed and reinstalled this extension but the screen still initially goes all the way to the right and then shrinks back to the left leaving a large blank space on the right. Does anybody know how to fix this so the space on the right is removed as previously?

Ok, Yahoo has forced me to the NEW format as of 6/3/19 I am not using any ad block software and only this extension and I'm seeing adds in that right panel. The extension worked very well prior to the forced change.. after not so much?! I see your updating and I appreciate your hard work and would like to continue to with the new format if you need more info leave a comment with contact info and I will look you up! Thanks! Stan B.

AD's Not loading but Ads panel or space is still there.need a new update for this Add-on.

Used to work great but the new Yahoo Mail has been out for several months and this extension hasn't been updated to handle it.

NOT AT This Time TO NEW at IT
