I use Adblock Plus ( https://addons.mozilla.org/en-US/firefox/addon/adblock-plus/ ), and I also have AdBlock installed ( https://addons.mozilla.org/en-US/firefox/addon/adblock-for-f... ), just in case the first one doesn't work. They are two of the most popular adblock plugins on Firefox. Or you could just use uBlock Origin on Firefox ( https://addons.mozilla.org/en-US/firefox/addon/ublock-origin )!
Please stop using AdBlock/AdBlockPlus. Use uBlock Origin instead.
Editing to say I've been reading on the fallout of the Chrome adblocking issue and many seem to think that DNS blocking is the way forward, but how long until it isn't? I've mentioned this before, but there has to be some way to do this without using browser-based solutions. I use them as well as a Pi-hole, but I dislike the browser-based solutions as a whole. What I'd like to see is a proxy, preferably web-based (cloud) that I can point my router and mobile devices to take advantage wherever I happen to be. Imagine a proxy that acts like /dev/null. It fools the sites into believing they are sending down ad data, but the proxy strips out that garbage. I know this does nothing for the bandwidth used, but I'm just thinking as I type. I understand HOW to do this, but my coding skills are not at that level. And I doubt this should be written in Python, although it likely could be. 20 years ago, I would be doing it in Perl, although those skills have fallen by the wayside since I have no real use case for Perl these days.
