If you want to help but find configuration hard you can easily help by running a Snowflake proxy on your phone or in your browser.
I have configured my phone run a Snowflake proxy every time my phone is connected to WiFi and charging. It’s automated and does not require me to do anything. I have turned on notifications that tell me every time I’m helping someone connecting to Tor. It gives me a good feeling every time.
privacy.resistFingerprinting breaks a lot more than just themes. Many of the weird problems reported in Firefox (and forks) are just from enabling it.
It has some pros but also TONNES of cons. Everything from a completely blank page to wrong timestamps to poor textures and so much more. Sometimes you will be flagged as a bot and prompted with literally infinite puzzles, thus effectively banning you from a website.
Some of these problems get fixed but new ones also get born. I personally use it but I also expect breakage and worse performance.
