That different browsers for different tasks is also something I’m doing now, although it’s not perfectly organized (yet).
With mobile browsers I have safari for most services and twitter / linkedin, firefox for banking and internal company things and brave for sites I’m not 100% sure I trust.
But at the same time I don’t have a Facebook account anymore (removed it back in 2011) and removed instagram about 2 months ago.
Things like the Light Phone 2 or Mudita Phone are coming to “force” people into good online habits and sometimes a little hard way may be the best way.
Discipline and restriction can lead to achieving more, and red-bubble micro-gratification simply moves that achievement to a “do later” list.
