I feel like Firefox is better. Or onion is probably even better. Set your privacy settings to strict. I use iOS and my results were strong.

Also go into your iOS settings and mess around. Disable all their bullshit. I’m not a super tech savvy person. My brother is in IT, but privacy is super important to me, so I go around, read stuff, turn off a bunch of their “share with” stuff, and their Siri bullshit and everything I can tinker with. There are a lot of iOS settings buried pretty deep in subpages. I’m not sure if the eff is checking those, but I’ve had to go down my list of apps and disable some Siri bullshit.

Sorry I can’t be more specific, like I said, I’m not the tech savvy one. I just use bare bones stuff, disable things that sound fishy. It’s all worked out for me so far lol
