It's a convoluted mess... See issue #12482. You may need to provide a PO Token. That said, I didn't yet have this warning (I download 1080p avc1/mp4a videos most of the time). Related?

Can you try: --extractor-args youtube:lang=en ? [Edit] Ignore that. That is for the title, not for the audio. Maybe first get the formats using `yt-dlp -F URL`. Then choose for example this to get this mr. Beast video dubbed in Russian: yt-dlp -f 136+140-1 https://www.youtube.com/watch?v=yhB3BgJyGl8 Or: yt-dlp -f "bv*+ba[language=ru]" https://www.youtube.com/watch?v=yhB3BgJyGl8

Yes.

Is it: https://repo.palemoon.org/MoonchildProductions/UXP/pulls/2768 ?

Same in New Moon. I don't even get this error window; browser just closes... [Edit] Browser also instantly crashes when trying to open the uBlock Origin dashboard. Reverted to previous New Moon (2025-06-17) and no issues.

@K4sum1 Could you try again with the new update? An important issue was fixed. I tried in my Windows 7 VM with the following command: yt-dlp --no-config -f "(bestvideo[height<=720]+bestaudio/best[height<=720])[vcodec!*=av01]" -t mkv "https://youtu.be/bCTObNkRGsg" And it gave me an mkv file with opus audio: Algemeen Unique ID : 57964954628617501393979581759164836982 (0x2B9BA4E945544816E3D80FC0D01CEC76) Volledige naam : C:\Users\Nico\I Built a Toilet Paper Slot Machine and It Actually Works!

I've always wondered about this as well. In the past I built Pale Moon on Linux a few times on my old Haswell i5 with 16GB Ram and it took about 20 minutes. PS, Supercomputers don't run Windows.

I've confirmed that version 2025.03.28.070132 still gives the right message: Current version: local@2025.03.28 Latest version: stable@2025.03.31 from yt-dlp/yt-dlp ERROR: Do not update the XP build with -U. Instead download from GitHub Releases again when a new version is available. Version 2025.04.01.080324 doesn't give the error message, but instead upgrades to the official x86 build. I must have forgotten to edit `version.py`. UPDATE_HINT = 'Do not update this build with -U. Instead download from my GitHub Releases again when a new version is available.'

What did I change? I can't remember having done anything to the yt-dlp release.

Yes, the same issue can be seen in Pale Moon (official).

Not only my youtube-dl. The official one doesn't work either. [youtube] PD-MdiUm1_Y: Downloading player 20830619 WARNING: [youtube] PD-MdiUm1_Y: Unable to decode n-parameter: expect download to be blocked or throttled See issue #33102

Yes, that was fixed 2 days ago with this commit.

Should be fixed with this commit. I've updated my build of youtube-dl.

Security by obscurity?

Even more important would be applying relevant security fixes from Mozilla (like Moonchild does), otherwise using this browser is Russian Roulette.
