uBlock, etc are for blocking ads and trackers. That means the trackers don't even load. Firefox Containers don't block ads, trackers, or anything. Instead, they isolate websites into their own "containers". Think of it like private browsing mode. Except each container is its own, separate private browser, and they persist. They're different approaches with pros and cons, but they can certainly be used together since they're orthogonal. Personally I use both. uBlock blocks ads/trackers/etc for me, while I use Containers as additional protection for not just social media sites but also to isolate my banking activity, work accounts, etc. It's useful for when you have multiple logins to the same site, and for mitigating some attacks (e.g. CSRF). [NOTE: I'm using the full featured Multi-Accounts Containers add-on, not the Facebook Container add-on mentioned in the article]

> uBlock, etc are for blocking ads and trackers. That means the trackers don't even load. That's what they advertise, but it's not even remotly true. I've made a bit of an exercice to see how they are working. Basically they all (adblocker and tracker removal) have a database of bad guys and avoid the known bad guys to load. The problem is all the unknown bad guy. We would need something that is behavior based, not database based, doing my research I couldn't find one that was working as one would expect. Just as 1 example of the bad guys: Cloudflare that send cookies when the owner of the site is using their CDN regardless if you have setup a do not track header. Do any of those track blocker managed to block Cloudflare? Nope It makes me sad that our community for some reason I ignore don't even respect the do not track header. It literally is just decoration

  It sounds like you're looking for Privacy Badger: it uses heuristics to block requests and cookies from third-party sites based on their behaviour in your browser. https://www.eff.org/privacybadger https://www.eff.org/privacybadger The basic rule is that if more than one first-party site tries to connect to the same third-party, that third-party could be tracking you and will be blocked. But it's a little cleverer than that, and has etra rules to just block cookies from common CDNs.

  > Do any of those track blocker managed to block Cloudflare? Nope False. I just visited cloudflare.com and uMatrix blocked 2 Cloudflare cookies, 8 Cloudflare scripts, one tracking pixel each from Bing and Google Ads (who are on the "bad guys" list), a script from Optimizely and an embedded frame from Google Tag Manager. That's with a whitelist that only allows CSS and images (the default, I think), and only from first-party sources. Surprisingly, the site wasn't even broken.

    I made my tests with: DuckDuckGo Privacy Essentials, Ghostery, Privacy Badger, Stealth mode. Never tried uMatrix and you're right, it's blocking cloudflare :)
