It is not that difficult to prevent private and important data from being leaked. It’s not about becoming invisible, just slow browsing with TOR behind a VPN with difficulties on many web pages. We must differentiate between private data related to the person and the activity, this naturally must be hidden or spoofed as much as possible, and on the other hand technical data, necessary for the pages to be able to display the content properly (screen resolution, public IP to display the correct language, operating system, desktop or mobile, etc.). This is data that does not compromise privacy when it coincides with millions of other users. All other can be blocked with a good ad/trackerblocker and some common sense to avoid the existing traps and dirty tricks used by the compañies.
Try Andi, it’s the most private (active privacy protection, anonymous, no account, no ads, no cookies, no logs, random proxie, own reader mode, watch YouTube videos sandboxed in the search results, apart the best in accuracy in an independent AI benchmark. I use it since 2 years as main search by default. https://andisearch.com/
