In a well-intentioned yet dangerous move to fight online fraud, France is on the verge of forcing browsers to create a dystopian technical capability. Article 6 (para II and III) of the SREN [sécuriser et réguler l'espace numérique] Bill would force browser providers to create the means to mandatorily block websites present on a government provided list.
--France’s browser-based website blocking proposal will set a disastrous precedent for the open internet
[Unfortunately one should no longer trust Mozilla itself as much as one did 10 years ago. If you do sign, you might want to use a fake name and a disposable email address.]
This bill is obviously disturbing. It could be that eventually they assume that .onion sites are all suspicious and block them, or something similar might happen, which would be bad news for privacy-oriented users including Monero users, for freedom of thought, and for freedom of speech itself. Note that the EU is going to ban anonymous domains too (in NIS2, Article 28).
For a regular end user, if something like this happens and if the block is domain-name-based, then one quick workaround would be using web.archive.org (or Wayback Classic), or ANONYM ÖFFNEN of metager.de (both work without JS). If this is France-specific, of course a French user could just get a clean browser from a free country too (perhaps LibreWolf or Tor Browser, or even Tails), provided that using a non-government-approved browser is not outlawed.
Mozilla, financially supported by Google, states that Google Safe Browsing is a better solution than SREN, but that too has essentially similar problems and privacy implications; especially Gmail's Enhanced Safe Browsing is yet another real-time tracking (although, those who are using Gmail have no privacy to begin with, anyway).
If it's DNS-level blocking, you can just use a better DNS rather than one provided by your local ISP, or perhaps just use Tor Browser. Even if it's browser-side, as long as it's open-source, technically you're free to modify source code and re-compile it yourself, but that may not be easy even for a programmer, since a browser is complicated, with a lot of dependencies; security- and cryptography-related minor details tend to be extremely subtle (just because it compiles doesn't mean it's safe to use), especially given that Firefox/Thunderbird themselves really love to phone home behind the user's back.

That should be easy if you do some script-fu, etc. Perhaps not so easy on Windows, though.
I understand that you may feel depressed, or even annoyed, for example when told, “Solving the problem foo is trivial if you use bar” when bar is not trivial nor realistic for you (or so you believe). For example, 2^149^−1 is easy to factor if you use elliptic curves, but studying elliptic curves may feel daunting (though it’s not so hard as you might think).
I do understand how you may feel in such a situation. I may be sometimes in a similar situation too.
Obviously, though, not trying to read about the solution bar wouldn’t solve the original problem foo. Not learning ECM doesn’t enable you to factor 2^149^−1 for example. Not trying to listen to about the L-word wouldn’t fix the annoyance of Windows. Annoyance itself may be harmless but everyone knows Windows is privacy-invasive and vulnerable to malware, viruses, keyloggers, etc. So staying too long there, refusing to learn some solution, something really bad might happen to you eventually. Honestly, something like that did happen to ourselves recently. Our community lost a lot of money, apparently stolen by attacker(s)—exactly what happened is still unknown, but the victimized wallet was on Ubuntu connected to Windows 10 via SSH.
You don’t need to ditch Windows. I respect your freedom to use non-free software. In fact, many L-word systems do include non-free blobs too!
That being said, may I suggest that you try different OS(es) just for 10 minutes, booted from a USB stick, when you have time, to see what it’s like. You might be surprised because it just works, actually more intuitive, you can use it easily, not to mention you’re not forced to see ads. Or no invasive telemetry. Feel free to ignore this suggestion if you really love Windows, thinking it’s the best OS ever. I respect freedom of thought!
