You should inform yourself before writing. And I say that without any harmful intent. To get a true privacy focused Browser you need to harden Firefox (and may download some scripts from github to do so). Or just use LibreWolf as it has a lot of tracking preventative stuff built in similarly to Mullvad Browser or Tor Browser. Those two are however of course still way better. The latter being the best with regards of anonymity if you know what you are doing.
I can just encourage you to inform yourself about the Firefox browser which is better than Chrome of course, but still compromises your privacy in the default shipped state.
It actually has encryption. Just no E2EE. The keys are just stored at Discord afaik. So the company should be able to read all of your messages. Just hackers shouldn’t be able to do so as long as they do not retrieve the keys.
For a great app with proxy (you can choose the proxy instance) use LibreTube. It is based on piped (which itself is based on newpipe afaik). It’s the best yt app i know and available in the default f-droid repo.
The way I understand it is that every anticheat needs to be overhauled as they can no longer tap into the kernel/get kernel access. So the anticheat has to run in userspace. This can also be done under GNU/Linux which is why anticheat should work on both platforms.
Why then not use Chrome if you are fine with Google?!
