1 - I use Firefox-ESR with the following add-ons:
uBlock Origin, uMatrix, HTTPZ, FireMonkey, CSS Exfil Protection, Header Editor, CanvasBlocker,
ClearURLs, Decentraleyes, Neat URL, Request Control, Skip Redirect, Smart Referrer and Temporary Containers. I follow this guide here: https://github.com/arkenfox/user.js/wiki/4.1-Extensions
I also modified my browsers config, using this

I don't use Tor yet and I don't plan to until I have a libreboot Thinkpad with a libre OS installed. Even then, I want to only connect to Tor via a VPN paid for with crypto.
2 - I dont particularly use IRC regularly
3 - I use Posteo as my email provider (Suggested by the Free Software Foundation)
Though I always access my emails via Claws.
4 - I like to watch Youtube videos on invidious.snopyta.org which is an open-source front-end of YT which prevents Google from tracking you. I always set the proxy server on so I can play videos without needing JavaScript.
5 - I like to use Signal and Telegram for my text messages.
6 - I use Paypal like most people do. I would like to use Cryptocurrency more often if I can afford it, though I did make a purchase with Monero once a few years ago.
If I have to use Bitcoin, I would like to use the Wasabi Wallet which anonymizes your BTC transactions via Tor as far as I know.
