There is not a perfect answer and unfortunately, the better the browser for privacy the less convenient:
#### For Desktop:
- Most secure ones (some sites won't work):
1. TOR Browser
2. Mullvad Browser
- Less Secure but way more convenient, you need to add extensions to upgrade your security and tweak your settings to remove browser garbage and improve privacy. They both support IPFS.
1. Brave Browser (you can sync across devices without an email account, quite convenient), profiles are quite convenient as well. VPN built in is paid only.
2. Opera Browser (you need an email address to sync devices, use a burner), the VPN built in is decent and with a free tear from the box.
#### For Mobile
- Most secure:
1. TOR Browser
- A bit less secure, but all sites work, requires tuning settings and adding extensions to improve security, as TOR, the Browser is FOSS.
1. Fennec
- Less secure and no extensions possible, needs privacy tunning in the settings, quite convenient and fast browsers for mobile, they both support IPFS.
1. Brave Browser
2. Opera Browser
