Sorry, but after installing this addon, the advertisments' videos did not disappear.
The yahoo webmail interface.

Still getting ads

I am still getting non-stop ads on the side why?

Kaspersky reports malware for this addon. Be aware!

chrome.storage.local.get(null, items => {
if (items && !items.adForSupportDismissed) {
var options = {
type: "basic",
priority: 2,
title: "Webmail Ad Blocker",
message: "Thank you for using this extension!\nIf you like it, consider supporting your developer with a contribution by clicking here.",
iconUrl: "images/icon64.png"
}

if (DetectClient.isChrome()) {
options.buttons = [{title:"Remind me later"}, {title:"No, thank you"}];
}

chrome.notifications.create("adForSupport", options);
}
});



Adware included. Stay away people.

This is a terrible extension as it does not allow you to choose if you want it blocking on all websites even on the ones you don't!

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.
