I currently use a few browsers on various platforms:

• Mullvad on Linux and macOS
• Firefox (w. Arkenfox User.js) on FreeBSD
• Safari (w. extensions & privacy settings changed) on iOS

However, I am finding the absence of any sort of cookie persistence in Mullvad and Safari to be a little annoying, as just about everything I use has 2FA enabled.

So, I was wondering what you would say a good choice for a second browser would be. I would use this to access a small number of privacy-respecting sites (such as CloudTube and Lemmy), which would involve saving cookies and allowing third-party content (i.e. googlevideo in CloudTube). Ideally, this should be Firefox or WebKit-based, and I would like suggestions for Linux, macOS, FreeBSD, and iOS.

On macOS, I have not signed in with an Apple ID, so I can’t use the App Store; but I do have Homebrew and pkgsrc(7) installed.

Any ideas?

EDIT: I am NOT moving away from Mullvad. I’m looking for a COMPLEMENTARY browser which I can use for stuff like CloudTube.
