It's not perfect (since its funding is mostly Google) but Firefox is my current browser of choice. It notably has very good support for blocking tracking and unwanted stuff thanks to uBlock Origin, which works best on Firefox according to its main developer [0]. And while it is funded with Google's money (which is a huge caveat), I still hope this changes in the future. Firefox could be funded differently. [By the way] maybe Mullvad browser is an interesting choice for this exact reason?

Other (independent) initiatives like NetSurf [1] and Ladybird [2] are on my radar. NetSurf has been around for a while; Ladybird seems impressive, achieving some great progress and result with little resources. I should actually try Ladybird more seriously when I get the chance, and maybe contribute if I find the time :-)

Probably the one from this post will now be the likely answer.
