Does Firefox containers hide your IP, device info and location?

Cash or monero.

As long as NewPipe still works, I do not care.

I like Thunder and Infinity

iPhone has the better reputation for privacy/security, however it is proprietary software and so no one can really tell for sure what kind of data that Apple might collect on you.

If you're worried about your government, then you shouldn't be using a VPN, you should be using Tor Browser to stay anonymous.

For general use, no it is not necessary. But it depends on your threat model, or exactly how private you want to be.

I suggest looking at the pages on FireFox by Privacy Guides:

FireFox privacy 2021 update: https://blog.privacyguides.org/2021/12/01/firefox-privacy-2021-update/

I didn't know that, thanks

It is FireFox that has hidden settings (about:config) adjusted for privacy. It refers to using a js file such as betterfox or arkenfox, or a pre-hardened fork of FireFox (Librewolf on desktop or Mull Browser on Android). You can improve your privacy by using a hardened FireFox, however you may also encounter more issues with website compatibility. It is a trade-off, and is usually only recommended for advanced users.

IceCat is over four years out of date

Brave is just a skin of Chrome

On Beta and Nightly it does, as well as forks like Fennec FDroid and Mull.
