Ads? Ah, yes the things that clutter up pages on other people's computers.
Really simple steps.
1) Install uBlock Origin on your browser. It nails everything, and hardly ever seems to trigger an ad-block detector. On this page alone it is blocking 19 "off domain" requests. It works for Chrome, Firefox and Edge apparently, but if you are using Edge, there is no hope for you.
2) On a home PC, just use Microsoft Defender. It works well enough and doesn't spam you.
That's it. No ads.
For mobile devices, either use something on the platform (these are rare), or the more comprehensive solution is to install a proxy that simply filters the ads out of your connection completely. I use Squid/guard, which does take a bit of set up, but works well.
The problem with clearing cookies is that all your default log ins for sites don't work anymore.
