Like, my firefox barely works without ad blocker due to invasive ads, how is this report being taken seriously? Ad Blocker doesn't cause problems
As stated in the report, the add-on was found to be loading remote code in every website, and in the extension page. This means that whenever you browse the web, the extension was sending a request to an external server, and that server could read and modify anything on any website that you were visiting. This is a serious security and privacy issue.
If you want to block ads, you could use a reputable blocker such as uBlock Origin - https://addons.mozilla.org/en-US/firefox/addon/ublock-origin/
If you really want to continue using this add-on (despite this report), an older version (3.0.0) is still available at https://addons.mozilla.org/en-US/firefox/addon/ads-blocker/versions/
