this must be a good add-on to stop ads on the right side panel of Yahoo!'s email client but it didn't work for me! it only works on the left side panel's ads but the top and right side panel ads are still there!

i think the problem is mostly because i switched to the new Yahoo! email client interface recently and it can 'bypass' such add-ons because another webmail ad blocker add-on did work fine on the previous version of the Yahoo!'s email client anyway ...

now, the point is, i like this new Yahoo! email interface and i'm not going to switch back really! the problem may as well be Firefox or Google Ads related because some websites do still manage to show off their ads ...
