If youtube is getting past ublock origin and demanding that you turn off your adblocker, here is a solution from reddit which worked for me: https://old.reddit.com/r/uBlockOrigin/comments/1hir4z6/youtube_filtering_again/m30vhjh/ After you uncheck the "ublock filters - quickfixes" box, make sure to also click "apply changes."
if you recheck the "ublock filters - quickfixes" box and click "apply changes," youtube will be able to detect the adblocker again, so i guess for now don't do that.
Edit from one day later:
They removed the comment, here are the steps they gave: 1. Open uBlock Origin's settings. I click on the shield to the right of the url bar and then on the gear icon in the popup menu to get there.
2. Go to the "Filter lists" tab of the settings page. Not "My filters."
3. Find where it says "Built-in," underneath that it should say " "uBlock filters" with a number out of five. Next to that "x/5," there should be an arrow either facing to the right or downwards. If it's facing to the right, click it so it faces downwards and expands the list of Built-in filters.
4. In that list, you will find "uBlock filters - Quick fixes." Uncheck the box to the left of these words. When the box is unchecked, click "Apply changes" at the top of the page. Refresh any pages where youtube was whining about your adblocker, hopefully the message is gone and you're able to watch without any ads.
Yesterday when I first posted this, reactivating the quickfixes allowed youtube to detect the adblocker, but as of today it looks like they've updated the quick fixes so that you don't need to deactivate them to avoid youtube's detection. So, instead of deactivating and reactivating the quick fixes, you can probably just manually update them by clicking the clock icon to the right of where it says "quick fixes"
