I spend a lot of time on Youtube, and their recommendations are addictive, so I blocked the sidebar that recommends next videos.

I block scripts on news sites since they serve no purpose.It removes things like popups, autoplaying videos and comments.

And I have so many custom filters set up to block cookie prompts, annoyances and other stuff.

Not a parent, but it's super-easy to block any element I find distracting with about two clicks.

For example looking at en.wikipedia.org I can just remove that COVID box. Scalable? No. Smart? Eeeyuh... Satisfying? Hell yes.

On news websites, beyond the typical heavy JS ads, uBlock is super useful for removing 1P static ads (e.g. New Yorker "subscribe and get a free tote" linked to as a newyorker.com image from next to an article) as well as things like sticky title bars and "top articles" widgets to declutter the reading experience.

You can use ubo filters to overwrite styles, saves you one extension

I don't use Facebook much any more but a lot of the noise on there can be blocked (the ads which are conveniently labelled as sponsored, and "suggested for you").

They've seemingly gone out of their way to make this difficult by putting each letter of "Sponsored" in its own div, but you can make a filter based on the aria-label instead.

Blocking Drift Chatbots (those annoying things that change Title in browser windows, make noise, obstruct page content)
