Shout out for pihole. Never ceases to amaze me when I end up on public data sources (cellular/wifi) and my phone is littered with ads and banners that squeeze the viewable area to a thin strip of screen. It's truly toxic. However, you can set up a personal VPN at home on the Pi and get your ads scrubbed by PiHole while you're away from home.
So yes, if I may offer my list (desktop browser):
PiHole (+ personal VPN to connect to when away)
uBlock Origin
Https Everywhere (for the odd site that isn't https by default)
Facebook Container ( if you use FB)
SocialFixer for Facebook - a godsend. I use FB for work and hobby groups. FB insists on cramming "suggested for you" content in everywhere. SocialFixer will filter and block FB posts based on text, and using "suggested for you" as a filter makes Facebook great again.
Duck Duck Go privacy essentials
EFF's Privacy Badger
uBlacklist - an app that lets you block sites in search results. A little tedious, but if you stick with it eventually you end up getting rid of many those awful boilerplate SEO worthless sites.
SponsorBlock for YouTube
EDIT: Guess I didn't answer the question? I despise ads. I will do most anything I can to avoid them. The aforementioned list of blocking and privacy add-ons is proof enough of that. There's nothing that I need to buy that I don't already know I want or need. I walk away from the TV (I can't remember the last time I watched network TV. Probably the primary election?), I put my phone down, and if it's that much in my face I simply close the site if I don't absolutely have to be there.
