I don't think I have ADHD but trying to read a news website without an ad blocker actually triggers me a little. The content keeps moving around as the ads are pumped in, and then a video (often unrelated to the article) begins to play, and it's often impossible to close it.

I'm unable to concentrate on the article. And then the ads change and a new batch is rotated in. Some of them try their best to obscure the content, they are all demanding my attention like screeching birds in the nest.

Firefox has an absolutely fantastic reader view (f9) which turns the page into something resembling an ebook with the ability to resize the font and adjust the pagination. All the distracting fluff is gone. Bliss.
