I use pi-hole and am grateful for it, but it breaks lots of online commerce sites (e.g. Amazon) in ways that irritate my wife, who then comes to me to file her grievances and tech support request.

This is AFAICT because it blocks "sponsored product placement" type ads — which are indeed ads, but which some users are deriving value from (at least so they think), and want to see.

(Luckily the admin dashboard makes it fairly easy to deal with these, but usually I "don't have time" right then and just disable it for x minutes.)

Ublock origin is the best here, since it blocks trackers and ads while still allowing you to temporarily click to bypass the screen that stops you from visiting a tracker (eg. a marketing shortlink or ad that you actually are interested in).

I agree that ublock origin is convenient, but doesn't do anything to block ads in apps, on (unrooted) TVs, etc.
