Vanessa Fields 2025-10-13: The ad blocker is definitely blocking the ads which is the most important thing, but it does not expand my screen so that I have more space.
Mark Granados 2025-08-03: Worked great when I first loaded it back when I first loaded it earlier this year. Stopped working after last Microsoft update in late July. Any suggestions?
slysnake96 2025-07-02: Nothing else seems to currently work on the big G's email service but this worked great, it's helpful for people like me who have Autism, OCD and ADHD and don't like change or being distracted unnecessarily.
Dallas McMillan 2025-07-01: Instantly works.
skygo 2025-05-28: Works perfectly! Thanks, Jason. Update 5/28/25 Still working perfectly. Thanks again, Jason.
kate tiller 2025-05-17: Works exactly as described. Thank you, Jason.
Amazing Ameya 2025-05-03: Jason Savard As of 3 May, "Webmail Ad Blocker” is not able to block outlook ads. Could you please look into it? Thanks again and great product! Keep this project alive 🙌🏻🤎
Dallas Even 2025-04-19: Images popping up, distracting me from my reading, the side of the screen being taken by the ads, and the inappropriate nature of some of the ads that I could not find out how to exclude are now all solved for me. This is still day one of having the blocker, but it works for yahoo mail fine so far. I will revisit and post a screenshot on the forum if a problem with it pops up. Thanks, Mr. Savard.
Runrofl 1 2025-02-22: Sadly, webmail ad blocker is no longer working properly on Yahoo mail, whether in Classic mode or the new, awful GUI that they are forcing users to adopt. The new interface lacks the previous settings we relied on, making the experience frustrating and far less user-friendly. It's a disappointing change overall.
Joseph G. 2024-12-03: Amazing Chrome Extension that will significantly reduce distractions in your day-to-day life.
Marc Bradley 2024-11-27: Very noice

William Corey 2024-08-12: This is brilliant, Jason...and I can't thank you enough, Godspeed in your next project.
Niall Bowie 2024-07-27: Works great. Yahoo now has an add banner on the bottom as well. Can you help with that?
John Paul Le 2024-04-05: it actually works. Thank you so much Jason. You are a godsend.
Kostas K. 2024-01-26: Hi Jason, Needless to say, I echo all the comments about how grateful the community is to you, for allocating time and effort on this - for a long time too !!! In case you have some spare time, Microsoft worked its magic on Outlook.com and ads started appearing again (bottom left column) :) Best, K
Michelle Bracken 2023-12-05: I've used this for years and it's perfect. I'm SO thankful for it as I have a small screen and this provides more real estate!

Jana 2023-09-06: It worked great on Yahoo Mail for over three years. However, as of 5th September 2023, it no longer blocks the ads on the right side. Very hopeful it will get updated soon.

S 2023-06-21: Decent, but room for improvement with Yahoo mail. the right toolbar gets messed up on yahoo mail web version with this extension. it removes the ad on the top of the inbox, but if you could fix the issue with the scrambled right-side toolbar, it would be highly appreciated and will change to 5 star.

Daveth XL 2023-05-06: 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.

Bill Ballmar 2023-01-24: 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.

Mary Anne 2022-10-13: This ad blocker has been working perfectly for a long time but today I started receiving ads on the right side of my Outlook mail. I hope there is a workaround as they are most annoying. Thank you for what you do. It is most appreciated.
