Privacy on the Internet is important because privacy risks range from the gathering of statistics on users to more malicious acts such as the spreading of spyware and the exploitation of various forms of bugs (software faults). Many companies, such as Google, track which websites people visit and then use the information, for instance by sending advertising based on one’s web browsing history. Sometimes prices on products are changed on the same website, depending on tracking information, and two people may view the exact same product on the exact same website yet be presented with very different prices.
I find this argument to be too extreme. Librewolf already acknowledges that it still needs to connect to some essential services but tries to minimizes which.
content-signature-2.cdn.mozilla.netfor example is necessary for OCSP (and HTTPS) to work, I’ve seen some blocklists block it in the name of “blocking telemetry” but it causes massive breakage. Just listing domain names isn’t a very useful argument.For HTTPS you can rely on local CA-Certificates perfectly which are upgraded by the OS.
The problem is that your offline CA stores won’t use OCSP revocation logs or certificate transparency. You need live updates for those. The latter is especially important, as without it you’re completely dependent on one group of CAs.
