Avoid non-free javascript and cloudflare mitm

archive.today is great; I use it a lot. It's the most generic method I know of; in other words, it works on a lot of websites. All of the other methods I know of only work for specific websites.

For some websites, I use LibRedirect [1], which redirects websites to front-ends for those websites, for example YouTube -> Invidious and Reddit -> LibReddit. Some of the redirects are not reallly necessary, and some actually lead to websites which require JavaScript, and I don't know if all it links to is free software.

For some websites, I use the Haketilo browser extension [2] to automatically inject free JavaScript to websites that normally require nonfree JavaScript, like Google Forms.

On some websites, I manually edit the HTML to make the website more usable. I usually can easily turn this process into a Haketilo script, and I have uploaded many to a git repository [3], but the ones that work are mixed in with the ones that don't and most of them are not very polished.

I also know about woob [4], which can be helpful in avoiding nonfree software, but I haven't actually used it myself. I think the official version of woob will sometimes install nonfree JavaScript and execute it like a browser, but maybe those modules are removed in the Guix version. I am not sure.

There are also some programs meant to interact with websites that normally require nonfree JavaScript, like yt-dlp (in Trisquel repos, may need to enable backports), some pidgin plugins [5][6].

LibrePlanet also has a (small) list of websites that work with free software [7].
