Email: (biggest change for me) ProtonMail or Tutanota.
If you’re going to have someone else host it for you, consider Librem.one and Kolab Now as well.
I personally like that both of them rely entirely on self-hostable FOSS for their stuff. You get the convenience of having someone else run your mail, but if their service quality doesn’t meet your expectations, you can take it with you. Not just the mail (which should be portable no matter what), but the software you’ve gotten used to. Very handy for non-mail niceties like contacts management and calendar, which don’t have a quarantee of a portable format across providers.
Honorable mention to Mail-in-a-Box if you go the self-hosting route. Ultimately, that’s what I did because I ran into a limitation with all of the hosted accounts…
I generate a unique email address and password for every account I create, and just alias all of those to a single main email address. Effectively, I only have one mailbox, but none of the plans I’ve investigated work well for that use case. Limits to the number of aliases you can create (or worse, charging aliases as users) becomes cost prohibitive very quickly.
Browser: I plan to use both Firefox and Brave. […] How many browser do you use?
Three.
FIrefox ESR is my primary browser, which is fairly locked down and highly customized for me.
Chromium is my “clean test” browser. With the exception of uBlock Origin and HTTPS Everywhere (managed by my OS), it’s completely stock. When Firefox gives me issues, I’ll fire up Chromium to see if it’s any better and figure out what is failing in Firefox.
Tor Browser is my “sketchy links and unknown sources” browser. The last thing I opened with it was a link for a game-related app sent to me in-game by someone I didn’t know. My suspicions that it was a scam where high, so I used Tor for it.
Search: DuckdDuckGo or Startpage?
DDG.
Startpage probably takes privacy and security more seriously, but DuckDuckGo has an amazingly handy set of features: bangs.
Password Managers: For this one I have no idea. Is it worth it?
Yes.
Bonus – News: I’ve been getting all of my news reading from Google Discover and damn I must say they do a good job at it. But with that said can you recommend any good privacy oriented news aggregation services or websites?
Roll your own using RSS.
YouTube channels are also RSS feeds, so you can “subscribe” to your favorite channels using RSS without actually visiting youtube.com.
Pair RSS feeds with youtube-dl and you can avoid a lot of interaction with Google on the video front.
