Good evening @SkewedZeppelin
First of all thank you very much for your reply, help and time.
Regarding search engines, I use the qwant lite https://lite.qwant.com/ gives good results and does not generate telemetry or anything weird.
Then the plugins help to mitigate the digital footprint that we leave with browsers, devices and others on the network. You can check it out at http://amiunique.org/fp as it is usually unique. Or traces and so on.
LocalCDN. (also open source, naturally)
As we cannot block www.gstatic.com nor www.google.com because they break the webs that require captchas, to minimize the tracking of the first we will install the extension (it also falsifies the cdns of the webs).
Inside the options (the little wheel at the bottom) we will give to Advanced and we will look for the last entry, Generate the set of rules for your advertising blocker. There we will choose ublock and paste those domains inside ublock origin, in the My rules section. (or Decentraleyes)
Cookie AutoDelete. Every time we close a tab in the browser will delete cookies from that site. It is highly recommended to set AutoClean enabled (with 1 second) and Notifications disabled. This way we avoid cookie problems.
Chameleon. Very complete tool loaded with lots of options to reduce our digital footprint. What interests us most is the ability to generate a different fingerprint every x time, otherwise we will always have the same one.
We will leave the real profile.
In the Options section, Injection, only the screen size should be checked, choosing 1920x1080.
The other options should be marked by the changes of the user.js so we will not touch anything else.
If some web gives error, we go to the section of White list, we give to Open in white list and we add this page.
Then in ublock I usually use: https://www.i-dont-care-about-cookies.eu/abp/ and https://raw.githubusercontent.com/hoshsadiq/adblock-nocoin-list/master/nocoin.txt , among others as https://gitlab.com/Jorgu81/hosts/raw/master/Mozilla/Mozilla or https://gitlab.com/Jorgu81/hosts/raw/master/Google/HostsGoogle
Then there are some recommendations in: https://victorhck.gitlab.io/privacytools-es/#webrtc or https://victorhck.gitlab.io/privacytools-es/#about_config , https://victorhck.gitlab.io/privacytools-es/, https://gist.github.com/0XDE57/fbd302cef7693e62c769#privacy-settings
As far as the user.js is concerned, Narsil’s user.js is based on arke’s one. But with changed things and adapted to mobiles. And it gives very good results and avoids a lot of connections. Besides I can assure that the creator of it, is very, very much in favor of privacy. And he is for example against Google or Mozilla tracking. And he updates it very often. Even as quindecim did at the time with his user https://git.nixnet.services/quindecim/mobile_user.js
He even has a thread to avoid Google https://m.forocoches.com/foro/showthread.php?t=6649428 or Microsoft https://m.forocoches.com/foro/showthread.php?t=7160249
And without discrediting the work of Arke that I also take off my hat with all his work and effort. But some automatic connection escapes.
Ideally, in Mull’s about:config you could delete the Google entries and leave them empty. To avoid telemetry. As you could do in the old Fennec versions of fdroid.
Thanks a lot for your time
