I think that using gecko based browsers like Firefox is the best thing to do in the short term. But having no competition is a bad thing. So supporting new web engines, like Ladybird, is important too: https://github.com/LadybirdBrowser/ladybird

It doesn't interoperate well with FOSS software like K9 and Thunderbird.
Thank you for your comment. Since I deactivated Google Play services, I don't get notifications on many apps. I didn't know there were alternatives. Unfortunately, the app server must be compatible, but if I can have it at least for Telegram with this fork, it would be a good start. I'll take time to compare the different alternatives and see if other push servers are compatible with more apps.
For what I understand, there are self hosted push servers, like NextPush that works on Nextcloud, and some that provide you a server, liked ntfy. For the latter, you have to check the privacy policy to see if it's better than the default Google firebase server.
I vote for political parties that are explicitly against facial recognition when possible (always a small party that nobody knows). I use cash.
Glad to see you use cash. It's often forgotten in privacy advice, despite being one of the most importants.
I think my first donation would be to GrapheneOS.
