Which Firefox add-on exactly you are using?

[JaegerMa]

I'm using https://addons.mozilla.org/en-US/firefox/addon/export-cookies-txt/

[dstftw]

Check YSC session cookie is exported.

[JaegerMa]

Yes, is exported as .youtube.com TRUE / TRUE 0 YSC <VALUE>

[dstftw]

Do you access youtube.com via the same network interface?

[JaegerMa]

Yes, the machine has only a single network interface beside lo.

[dstftw]

I mean do you use the same external IP? Browser uses v4 by default while youtube-dl may use v6.

[JaegerMa]

Yes, I also did the test with IPv6 disabled.

just wanna thank @JaegerMa for reproducing this reliably and @dstftw for working to address it. I know I'm not the only one who's been fighting this intermittently for ages
