Install an Ad blocker. I'd recommend uBlockOrigin on Firefox, or Firefox for mobile.

I mean just in general it makes the web less awful. Webpages are so much easier on the eyes without all the crap they try to stuff in there.

And it can prevent malware, especially for those less tech-inclined.

And it means you use less data/bandwidth, since the blocker prevents the request from ever being made in the first place.

If you want to support a site, just buy a subscription or donate to them or something.
