FWIW
I don't randomly surf so much so there are very few sites that I have a problem accessing. But when i do anything online I use the following methods, in descending order:
1. Tor
2. Mullvad
3. DuckDuckGo (also go-to for any YT videos)
4. If none of them work then I don't need to access the site.
I know that this article only focuses on browsers but browsers are only one part of my snoop-avoiding suite.
I use a VPN, Little Snitch, a virus/malware checker. I use E2EE for cloud storage, texting, email, voice, and video with whoever in my very small circle is willing to do the same.
Each online organization gets a unique alias email address so I can specifically change/block that email address without affecting any others. Also very handy in figuring out who has sold my information. When I discover that has happened I send an email to the organization informing them I don't appreciate their selling my information. In one case an investigation on their end revealed a breach and I received a thank you response.
Due to their limitations I do no surfing on my phone or notepad. Old school; whatever it is can wait until I get home where I have all the privacy tools I can think of on my desktop.
Do I think I have all the options covered? Emphatic >nope< on that one. But its good enough for now until I encounter something else I want to add.
All time favorite quote from the movie Anon: "It's not that I have something to hide; I have nothing I want you to see."
( I usually paraphrase it as, "It's not that I have something to hide; I just have nothing I want to share with you." Ever so slightly more "in your face" than the original quote. )
