Sorry, but after installing this addon, the advertisments' videos did not disappear.
The yahoo webmail interface.

Love it. Emails now readable without strain!

Damn Outlook just refuses to send e-mail/attach files, throwing error messages at me repeatedly unless I refresh the damn page several times.
Installing this Ad Blocker is like smacking Outlook in the face with a flipper, setting it back to factory default, reminding it that YOU ARE A GODDAMN EMAIL CLIENT. Now, Outlook just does its job perfectly. No glicth. Can you believe that?

THANK YOU SO MUCH. Works just as intended

was my go-to ad remover, but yahoo found a way to tell if this is running and they will nag you about incessantly until you turn it off

It seems to be blocking the new Yahoo Mail ad-blocker pop-up that uBlock Origin was letting through. Great job!

It cannot disable the whitelist pop-up on the right in Yahoo!Mail.

Would you check it please.

Sincere thanks.

***Stay well and safe!***
