It works pretty well. I had increased lag for a bit and it seems like the guy fixed it. He appears to be doing a great job with this project and I respect that. I'll need to remove it as it stopped working (I assume it's because I haven't paid). I wish it was free as it looks legit but I'm not making enough for it. Great experience though and the creator looks like he's making improvements still! Good Luck!

It's just stopped working as of yesterday and nothing I can find seems to make it work again. It's also ironically asking for money now...

I like this plugin and it works well for me. Unfortunately, from the Github: > I am no longer the owner of the extension called "FadBlock". I handed the extension off over a month ago, seems like it traded hands a couple of times, and now the current owner has added malicious code while keeping the extension as it is! https://github.com/0x48piraj/fadblock

Is FAdblock Safe?

Risk impact
Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

FAdblock requires a lot of sensitive permissions. Exercise caution before installing.

Risk likelihood
Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.

FAdblock is recently added, and hasn't been around long enough for us to gather enough data to accurately assess its risk level.
