force tracking protection to strict mode

quoting myself over and over:

strict mode is actually the only mode that makes sense, for a number of reasons.

there's nothing to gain in custom mode honestly, the other cookie settings would disable dFPI which means turning off isolation in the browser.

my view is this:

  • 99% percent of the users don't know that strict mode = isolation, so they think it's fine to disable it.
  • 99% of issues that user think are being caused by strict mode are caused by something else.

I wrote some similar thoughts here -> https://librewolf.net/docs/faq/#what-is-mozilla-tracking-protection

keep in mind that currently changing mode requires overrides anyway. I do not expect breakage, if anything this reduces breakage caused by blocking third party cookies while adding isolation. FPI is not something we should consider as dFPI is its successor which is actually being supported and developed and all that good stuff.

@maltejur proposed changing the UI in this way -> #147 (comment 844601862)

tasks:

  • write proper description for UI;
  • take decision;
  • update docs;
