This seems promising. It lets you block sites from showing up in your search results so you can shitcan Pinterest, w3schools, etc. The first time you do a search, you have to bonk the extension icon and give it permissions. There are also a bunch of blacklists you can subscribe to here.

The enshitified web throws at us websites with autoplay videos that waste copious bandwidth. The waste is not just annoying and eco-hostile, but it sucks dry the credit of people on limited internet connections and grinds CPUs of #permacomputing folks to a crawl.

The best fix in principle would be a browser that disables animations. But it does not exist (reference). It’s an extremely complex problem because there are so many different ways video can forced on people with JavaScript. The developer of Ungoogled Chromium gave up on the effort and even Google have failed in their attempt as well (yes, I shit you not, the big brains at Google could only figure out how to mute the audio).

So the next best option is to identify websites that autoplay video and cancel them. The #uBlacklist plugin is available on Chrome and Firefox. When you get burnt by a shitty autoplay website, you can blacklist so it doesn’t happen again. There is also a mechanism to subscribe to crowd-sourced lists.

Caveat: I’ve not used it myself as the plugin is incompatible with my browser version. It appears it supports certain search engines which I do not use myself, so I’m not sure if it’s useful apart from search results on particular search services.

⚠ The link to jwz.org might have autoplay content, ironically enough. Sorry if that triggers on anyone! Tor Browser is exceptionally able to block the autoplay on that site, so I suggest using TB. I do not like the idea of publicizing MS Github but this link is an alternate which is linked by jwz.org anyway.
