> I guess your local proxy (why?) Not GP, but if it reliably blocks YouTube ads I think a lot of people would be interested in doing that? As you say it's not possible via DNS; so can only be achieved in the browser, and in browsers with uBO. (I.e. not mobile apps, Android TV app, mobile browsers other than FF on Android, desktop browsers other than FF/Chrome/derivatives.)

  How does uBO accomplish this. Perhaps certain requests are necessary for ads. If true, then one way to avoid the ads is not to make the requests. This a guess: When we MITM our own traffic on our own network using a root certificate we make ourselves with openssl, the graphical browser may try to annoy us and makes us "click-through" a warning. It may effectively block a request. If the request is for an ad, then ... TBH, I am not convinced that I have a solution that works on every video. This is why I ask for examples. However I never see ads with the videos I watch, so it does work on some. I generally do not watch stuff that is heavily commercialised. Also I normally download the entire video before watching; I dislike so-called "streaming" and Javascript video players. I need more examples I can test. All the videos submitted to HN seem to work. I need other examples.

How do you do that? It's probably that. (That's also unfortunately a browser / 'use a different app' solution rather than something that'll work for the YouTube app on iOS/Android/TV devices.)

      There are two types of YouTube ads, right. The pop-up (pop-over) and the "pre-roll" (today, periodic roll). IOW, the ads are either opening in their own little window or they are themselves video files. Does DOM/content manipulation mean certain .js is not run. For example, requests for that .js is external and are not made. When I am testing people's claims that YouTube ads cannot be "blocked" except with uBlock, I am using the same graphical browser that most people use. I do not believe these claims. I can prove there are other ways to retrieve videos without retrieving ads. When I am not disproving those claims, I use the commandline (netcat + TLS proxy + ftp) to download video. This is the fastest and easiest way to use YouTube for me. It is extremely simple. No python required. Just some simple URL decoding and a little grep. I see no reason to use the graphical browser to download video. Thats overkill. Thats why people end up seeing ads, IMO. I may use the browser for playing media files offline but not for making HTTP requests.

        You can stop certain js files from running, but it's way more fine grained than that. Blocking external scripts would lead to massive breakage. If you wanna know how ad filters work, look at a filter list: https://easylist.to/easylist/easylist.txt https://easylist.to/easylist/easylist.txt > I can prove there are other ways to retrieve videos without retrieving ads. Go ahead? There is no technical reason why Google can't serve you ads. You are not using DOM filters and we've already established that your DNS filter has no effect on YouTube. Google is choosing not to show you ads > I use the commandline (netcat + TLS proxy + ftp) to download video > URL decoding and a little grep Eww, that'll break every time YouTube changes their ui. None of that is necessary. youtube-dl works with pretty much every video site, does not require a wacky setup, and it tracks YouTube changes pretty much instantly. It also works with playlists, entire channels, etc. You'll spend years replicating all the little features like quality selection, subtitles, etc if you use shell scripting for that.

        "Eww ..." Funny, that's the reaction I have to python and youtube-dl. Aesthetics play a role in our perception, I guess. If youtube-dl were smaller, faster and less brittle than a few lines of shell script, I might use it. However it fails on all three counts. I have only had to make changes to scripts twice in the history of YouTube. youtube-dl is constantly breaking and being updated; an incredible amount of size and churn for something so simple. I never have to wait for someone else because I can fix a script and be downloading again in the same day.
