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.

Worked great until today. I gave it 4 stars because I'm hoping the developer will fix it ASAP. When it's working, it rates 5 stars.

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

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

The extension is very useful for people who are curious about what font a page is using. However, my problem is that it slows Firefox down dramatically on my computer (Fedora 22, Firefox 39, 2.2 GHz dual-core with 2 GB RAM). I know, not a high-end machine, but without this extension, everything is pretty snappy. I use several other extensions and none of the others have this problem.

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.

fine.

Works great! Thanks!

Ta!

Keeps opening webpage of WABInstall (https://jasonsavard.com/?ref=WABInstall)
And im tired of it, so uninstalling good riddance !

I cannot sign-in or comment thru links provided on wab website, so i have to do it here.

So, it's true... the redirect glitch is directly related to setting Firefox to clear history upon closing. Any other combination of settings seem to work fine. It appears there is no immediate solution other than to not use the extension.
