AdBlock Edge (doesn't have /acceptable/ adverts, which ADP has)
Interesting. I was behind on the news. Thanks.
BeefTaco
As you are perhaps already aware, these are not the same thing in a couple of respects. First, Disconnect is a fairly complex piece of software, installed as a browser extension, that aims to intercept tracking requests and selectively ignore them with per-site whitelisting and blacklisting controls. BeefTaco, by contrast, is purely and simply a set of preemptive HTTP cookies (with effectively infinite expire times) one loads to prevent known tracking cookies from being deposited. Second, Disconnect is (in part) proprietary software.
CertificateWatch
Looks interesting.
I am not entirely convinced it does The Right Thing, or even how best to consistently use the information it provides, but its seems like a useful tweak: Again, like BeefTaco, it has the benefit of being a simple concept implemented in open source: It pops up to inform you that an SSL cert or attestation has changed. That's it. That's all it does. It's up to you to decide whether the change is worrisome or not -- but at least you know and are not gliding along in blissful ignorance, not knowing that (say) Reputable Ltd. attested to a cert yesterday, and that it's been replaced today by a different cert signed by some obscure certificate authority owned by Ukrainian mobsters. In other words, it's a first step in getting away from the 'Somebody your browser designer once considered reputable signed thsi cert, so that's all you deserve to know' model of HTTPS.
