Finally got rid of that pesky sidebar. My ad blocker was already blocking the ads but Outlook was complaining about it, saying that I should upgrade if I want to get rid of ads. What a relief.

Now please, also get rid of that 'Upgrade to premium' button on the lower left :)

I have definitely enjoyed this addon, and it works great (except for a few quirks on the nightly versions of Firefox, however I am perfectly alright with that, as it was my decision in the first place), I also put it on my family's PCs as a result.
I have noticed that it doesn't work on Yahoo Mail's latest beta (I have verified this on the stable version of Firefox) , and only because I have uBlock Origin installed, the advertisements themselves don't show.
While I don't use Yahoo as often, ever since I had moved over to ProtonMail, it would be nice if WebMail Ad Blocker would add support for the new beta interface on Yahoo Mail.

hotmail and outlook accounts have the same interface,So it's weird why this happened.

same title:just weird

pls take a look,Thanks

Works just fine! Contrary to OTHER ad blockers... this one really blocks ads in my outlook mail page (www.outlook.com)

it works great

Webmail Ad Blocker has been a great addon for Palemoon. However with the Update to Palemoon v27.0 the extension no longer works. If you could find the time to look at this it would be much appreciated.
Thanks

Very useful tool. Works great!

It's a useful tool! I use the hotmail (outlook.com), and it has advertising in the right side. After I use this addons, the advertising disappear and have more space in the right side! Thank you! In addition, I hope our privacy can be guaranteed.

Works great! Thanks!

Ta!
