You might have noticed that even on Firefox (depending on your lists) YouTube may detect uBlock Origin on Firefox now
There's already a workaround (found, again, here), but I figured I would use this opportunity to tell people that projects like Piped and Invidious exist, which both allow you to watch YouTube without loading their ads, with improved Privacy and (in the case of Piped) even Geoblocking-Circumvention and SponsorBlock out of the box.
They're both great tools, and using something like LibRedirect you can even automatically go to Piped or Invidious when clicking/opening a YouTube link (and more).
Both don't load ads, but unless changed in the settings Individous may still make connections to Google/YouTube to load the video(s) themselves.
Bit of a shameless plug for these projects, but I figured this is a really good time to show these projects as I often see people asking what they are in threads on here
When the sponsor is baked into the video itself, there's no way for the advertiser to know how many of the people who watched the video, skipped past the sponsor. The only way they know wether their ads are working or not, is by seeing how many people used the discount code from said channel. If you're the kind of person going thru the effort to install additional software on top of adblocker to get rid of this sponsored content aswell, I think it's quite safe to assume you weren't going to buy their product anyways.
Also if you're still feeling bad about it, just donate few bucks directly to the content creator. That's way more than they're ever going to profit from you watching ads anyways.
