Zen is basically Firefox with different UI. It is a security/privacy downgrade from Librewolf. You can configure Zen to have the same security/privacy settings by putting about:config in the URL bar change some of the toggles.
Use either the Arkenfox (also available in the interactive live viewer online) or Phoenix user.js as a template. Basically: disable WebGL, set WebRTC to disable nonproxied udp, disable JavaScript JIT, enable privacy.resistFingerprinting (optionally enable privacy.resistFingerprinting.letterboxing for screen fingerprint protection) and some other things.
Phoenix has some configs for Zen iirc which you can just patch. It is less strict than Librewolf when it comes to fingerprint protections (softening some of RFP's protections).
If you want to test that the fingerprint protections are working, use this test site by Arkenfox called TorZillaPrint.
Beans are far more versatile imo. Soy alone is sooo useful to me as a vegetarian.
Now if instead it was nightshades vs legumes, I would have a hard time picking because tomatoes are the best, and so are potatoes. And what would I even do without peppers and spicy food.
But legumes have so many amazing plants like soy/black/chili/garbanzo beans and peas. TVP is made usually from soy or pea protein and is a super useful source of protein. Legumes are also "nitrogen fixers", meaning they produce bioavailabile nitrogen rich soil.
I think I would have to give the win to legumes because I can survive on a diet predominantly filled with legumes but not really just potatoes/tomatoes/peppers/eggplants. I need protein.
