  • (2023-05-06) Daveth XL: was really hoping it would block the ads in my inbox, as that's what I'm looking for right now, but it didn't. And there's only 3 options, which are to enable or disable it for certain sites.
  • (2023-01-24) Bill Ballmar: It used to work but now yahoo email shows ads on the right side, I uninstalled reinstalled start yahoo email and the ads still show up so this is getting past the extension block. As others on the site support have stated it's not working anymore.

  • (2022-08-24) Hasan Sarptaş: It works perfect. But why the extension does not block AOL Mail ads. It uses Yahoo infrastructure. This is a feature request!
  • (2022-07-25) Paolo Rainone: It doesn't work with outlook, at the moment!
  • (2022-06-29) DSE Bio 生物科自學區: This is one of the essential extension for me for years. But on this week there is a line of ad shown on the top in-box... I am very worried that there will come the second and third one that mixed up with my inbox mails...

  • (2022-05-23) Music Mayer: Great overall. I do notice that ads still show up but quickly disappear, most notably but not exclusively the top-line ads... so is this just hiding them or actually preventing them from loading? Also, ads still show up when performing searches in Yahoo mail. Anyway to block those? Still very glad to have this though!

  • (2021-01-17) John Canfield: I installed your Web Ad-blocker while hovering over my e-mail website (nameless here). The second i clicked the icon and enabled the ad blocker, the ads disappeared. Refreshing the page gave me a full page screen to view my e-mails. Great, no wading, with no waiting! Thank you. At first blush, appears to be a wonderful service.
  • (2020-12-05) Jaybe Leblanc: Pour les utilisateurs de Yahoo en cette période "anti-adblock" ça marche à fond :)
  • (2020-11-25) CRZ: This was a fine working extension but seems not to be working well anymore!

Thank you

    Hi, Thanks for your Firefox add-on, but I find that I am unable to attach a document when I am composing emails in Yahoo mail when your add-on is running. If I check "show advertisements" in the Yahoo tab under preferences, attaching works. If it helps, I also pay for a preferred version of Yahoo mail. Thanks, Andrea

    In the new version of Yahoo mail, Webmail Ad Blocker leaves a section of the toolbar blank and does not let the toolbar extent all the way to the right. Thank you.
  • (2013-03-14, v:3.2) Simon Welch: AdBlocker - Yahoo Mail
    Jason A great application, thank you. I've started using SlimBrowser, given that Firefox keeps crashing on me and Google is starting to look more like the "Evil Empire Mark II". It does not appear that AdBlocker is working on this (still obscure) browser.
