Still kind of concerned about the future of this extension, also wondering why the author didn't decide to change the name of the extension to distance the Firefox version from the Chromium version (the Chromium version was bought out and is no longer safe to use).

Aside from that it is pretty decent, I personally use it alongside uBlock Origin on FF (I never used it back when I was on Chrome years ago). It works very well, just make sure you go through the proper setup if you use it with uBlock Origin.

I was able to add the filters for Step 2 and Step 4 in the uBlock Origin settings,
Extra installation steps for uBlock Origin Step 1 Adblock Warning Removal List. Cannot be added.

Ok, I have enough of it (of getting this to work). It looked like the devs fixed it, but here's the issue:

Installed Nano Defender and Nano Adblocker to keep it simple. Both from AMO. Doesn't work on certain websites though. For example for imgView.net, https://imgrock.pw/ , https://imgtown.pw and so forth.

Tried the quick issue submitter, but it gave me a hard time. It said the issue is fixed. Maybe it was, but it's not anymore. So I was required to go to Github. Little bit too nerdy for me. Spent half an hour just to find a unused username to sign up.

I did try to add the issue, but I did it wrong and I can't be bothered to "study" how to report an issue. You almost need a license just to be able to report something. I'm happy with simply being an end-user.

Two stars for the effort because I don't like 1 star. But right now it hasn't been a success for me.

Edit: added a star because it looks like the devs are really trying. This is a toughie though.

Edit 2: added another star (to 4) because it does a good job overall.
