MUST HAVE BROWSER ADD-ON!

Seriously, this add-on is amazing. It's the swiss army knife of Firefox add-ons. It blocks ads, trackers, malware, spam, scams, annoyances, etc. You can configure it to do whatever you want, whether you are an advanced user, or if you're just a basic user, the default options will do fine.

It's easily the best ad blocker and content blocker overall that I've used. It's easy on resources, super easy to turn on and off, and gets the job done. I think everyone should have this extension honestly. Once you get it, there's no going back.

Addon fails to block ad-videos on most famous streaming-site Twitch.tv, the ad-videos that run before the actual stream-content.

One of the VERY FEW addons that is really good and works well. Easy to block objectionable images on webpages so as to deny them ad revenue, like with sites that mistreat users. Only criticism I have is that when using an encrypted connection like with a vpn or tor, the settings do not stay and you have to reset the blocks. I'm guessing its because the ips and other stuff changes with tor so cannot make the blocks permanent. Great extension over all. Look for other add-ons by this author they will be good.
