This —- I really don’t care if my blog with no user registration or comments gets accessed over HTTP/1.1 without an SSL cert. Further, I find the way Chrome handles HSTS pretty gross, as some of us actually tinker with stuff that REALLY doesn’t need encryption, like little dev boards and projects running locally. Chrome makes those exceedingly difficult to use, thus the need for extremely convoluted workarounds like…
I do care. I don't want to have my name attached to any advertisements that shady airport routers may insert into the html for instance. TLS is a very good thing and we should have more of it, not less. Sorry that your unupgradable software comes from an era where security was not important.
TenFourFox[1] continues to be maintained through community effort, and receives regular security fixes/backports. The problem is not software (although the project desperately lacks manpower), but the 20yro single-core CPU that literally sweats to push the crypto (let alone the CSS&JS).
Don't get me wrong. The relentless push for TLS is good, and I'm not arguing to take a step back - that would be insane. The change I'm asking for is, rather than doing [2] in your nginx.conf, do [3]. It doesn't change anything at all for modern browsers (when you hit that path, you're already at the mercy of an intercepting proxy), but makes your site more accessible for my ancient junk ;)
