ff2mpv VS stylus

It is. And you can use it in your (desktop) browser with an add-on: https://addons.mozilla.org/en-US/firefox/addon/ff2mpv/

FWIW there is a GitHub repo [0] which keeps track of currently-working ways to block Twich ads. If you don't need chat, ff2mpv [1] can be used to send streams directly to MPV by right clicking on them in the browser. This bypasses the entire proprietary Twitch frontend and displays a silent purple screen during ad breaks.

Unfortunately this won't work with the extension playwithmpv unless you modify the python server to launch a different command. I personally use ff2mpv and I modified the python code of the backend to make this change. If you are interested, this is what I changed on ff2mpv:

There are also browser extensions that add a toolbar button and a link context menu option to automatically open videos from quite a number of popular sites in MPV. I'm using ff2mpv. It only took a minute to set up.

You can use a browser extension like ff2mpv to send the urls directly from your browser (so no need to type into the terminal). This works not only in youtube but in many sites as yt-dlp has support for multiple pages.

If Firefox still uses too much CPU, then I recommend ff2mpv -- It does require changing your habits a bit, like blocking autoplay and clicking ff2mpv to launch the video in mpv when you're ready to watch, but it is well worth it.

With Firefox, use the extension ff2mpv to play anything supported by youtube-dl with mpv player.

I used a Firefox add-on called "Stylus" and wrote a custom css rule to hide the relevant divs/elements. It's not perfect, but it's okay. https://github.com/openstyles/stylus

However, after the recent ad-blocker targeting by Youtube I pretty much just stopped watching. I added my regular subscriptions to the NewPipe app on my phone and just watch what they put out.

The add-on I mentioned above is super useful to personalize my experience with other websites. Particularly online-shopping and other marketplaces that have huge amounts of whitespace for no reason. You'd be surprised how much nicer the web experience is after you add a few "margin: 0px;" css styles to strategic areas.

I try to maintain a user style to improve Fandom's wikis, for anyone using the Stylus Extension.

Both of these are hosted on userstyles.world. To use them, you'll need to have a browser extension like Stylus . Then just click the blue Install button for each tool you want!

These are both hosted on userstyles.world. I recommend using them with the Stylus browser extension, which works on Chrome, Firefox (including Firefox Nightly for Android) and Opera. (Pretty sure it will also work with Cascadea if you're on Safari but I haven't tested it yet.)

I wonder if Stylus would be good for this...

Use Stylus

Stylus and display: hide !important; are your friends.

looks good to me, its a css file so its already quite limited, and i did a quick check and it doesnt seem to load anything (from just searching for "url"), so it should all be local. stylus is open source, but of course thats no garuntee that its safe https://github.com/openstyles/stylus . its also a reccomended extension on firefox, which means that they do check it more thouroghly, but idk if thats good enough for you.
