Privacy respecting search engine. You should definitely replace your current one with something that doesn't track you.

An alternative to Chrome from a trusted privacy oriented company. You can never be fully sure that Google is not adding something suspicious to their browser. If you do trust chromium though, or something based on it, then you should totally check out the alternatives.

This is the grand father of good adblock. Sure, it's interface might not be that pretty, but it sure does it's job really well. You might wanna checkout Nano Adblocker though if you want something a bit more fresh.

Limits all kinds of trackers and ads. Might be a bit too much for most users. But it's one of the best ways to limit the attack surface for tracking you.

The way to go if you want truly secure communications.

Matrix is a federated communications system, which provides excellent security and privacy. But currently it still feels a bit unfinished, so make sure that you can bare a few rough edges if you're going to start using it.

Secure email that works. There are other privacy focused email providers too, check out the alternatives if Protonmail isn't the one that you'd t rust.

If you want at least something that claims to not to track you and doesn't have the worst reputation, and you want your messenger to be usable, you might wanna check out Telegram. Though again, it's privacy is debatable.

A very good and open source 2factor app.

You can get Android apps from something that isn't the Play store.

Replaces google's password manager. There's also Android apps that can use the KeePass database file. Something that keeps your database file always offline guarantees that nobody else can access your passwords.

Integrates KeePass into Firefox for autofill. This is more of an "ease to use" thing, it's security might be a bit questionable though, so only use this on very trusted devices.

Better than your cloud provider spying on you. You could use this to sync your KeePass database file.

Replaces Google's calendar and contacts sync. Or alternatively, use caldav and webdav.

If you don't use YouTube for anything, and only need a place to upload videos, Vimeo will be fine for you.

It's YouTube without any of the personalized trackers, and a bit less features.

If you like RSS feeds and already have lots, you can combine invidious with this, or just accept some YouTube trackers and use YouTube trough embeds. I use an userscript ( https://greasyfork.org/en/scripts/1760-youtube-rss-feed ) to get the channel RSS feed urls.

This is quite easy to setup on a raspberrypi. It's dns level ad blocking, but it doesn't catch everything. But more layers of security usually is better than less layers.

This is almost usable as a regular OS.

Nobody will be reading your messages if you GPG them

Why not setup your own VPN too, so that you can use it as a proxy to your real vpn maybe? Buy a cheap vServ, setup OpenVPN to listen on port 443, and you've basically made yourself a really good firewall bypasser.
