Except sites deliberately break themselves if they can't harvest your data. You can't even browse reddit on Tor anymore.
Even merely using Fennec on my phone, I encounter shopping sites where I actually plan to spend money refuse to work because they can't recognize "my device." Or they refuse to sell me products where I live if I'm using a VPN. Creepy-ass behavior.
I suppose the only way out is through, and we should simply refuse to use sites that are designed in such a way, but it feels like a losing battle.
Trying out Librewolf, I realized just how many sites (including Reddit!) use tricks like canvas fingerprinting to identify me up to 99% uniqueness. And here I thought just a VPN, uBO and no cookies would be enough!
Lots of ways to track besides cookies. There are many ways you can fingerprint a user. It's actually pretty hard to not have a unique fingerprint on the Internet.
I wouldn't recommend deleting all cookies all the time. While true, it does make more private, but relogin into all the sites all the time is a pain.
While while listing is good, I'd recommend a separate "burner" profile that essentially reset itself on closure, with all the privacy options activated.
Then, you can have a second profile you can use when you need to be logged in.
I literally have librewolf open on profile switching so I can easily have my reinforced profile ready to go.
I don’t know if there’s a reason to this, but on a lot of sites, clicking “manage” and then “save” seems to give some good defaults - like maybe they need an affirmative action to “turn on” eating your babies settings.
