It's most likely Youtube's fight against ad blockers. When opening a video, check the bottom left corner. Sometimes there is a message saying "Experiencing interruptions? Find out why.", which will lead you to a page blaming ad blockers: https://support.google.com/youtube/answer/3037019#check_ad_blockers&zippy=%2Ccheck-your-extensions-including-ad-blockers

You can try to disable your ad blocker to see if it still happens (or use a private window without extensions). Alternatively you can try another ad blocker like uBlock Origin, which is pretty fast in fixing issues most of the time.

I have seen that before, but with those instances, the page actually otherwise loads properly. With all icons and even the suggested videos coming up properly. Here, that's not what happens. But it could indeed be them fighting ad blockers again. I wish they'd knock it the hell off. All they did with that is just anger people and prevent any chance of people giving up ad blockers, especially since there is literally no quality control on Youtube for that kind of thing, and nobody wants to risk malicious ads getting airtime on their computers.

Is Mozilla looking into finding a way to prevent ads natively? Like I said, I've heard there's a browser that can do it, so I'm hoping other browsers will follow suit.

As far as I know, there’s nothing official yet, but there might be something coming: Firefox Has Quietly Integrated Brave's Adblock Engine

Yeah, they seem to think annoying people will somehow make them like Youtube more instead of tryign harder to fight back. Pretty sad, really.

That last bit is something I hope is legitimate. Will we know if that becomes a legitimate thing, and how will we be able to set it? Will we still need stuff like the various adblocker extensions when/if that goes through, or what?

Hi,

The people who answer questions here, for the most part, are other users volunteering their time (like me), not Mozilla employees or developers. When a Mozilla employee jumps into a discussion, you'll see the Mozilla Staff label next to their name.

If you wish, you can leave feedback for developers on the Mozilla Connect website. Click the Firefox Menu button in the toolbar, click Help and select Share ideas and feedback…. Alternatively, you can use this link. Your feedback is collected by a team that reads it and gathers data on the most common issues.

You can also file a bug report or feature request. See File a bug report or feature request for Mozilla products for details.

Please note that this is something being considered to be used in tracking protection, NOT in blocking ads natively (see [https://www.reddit.com/r/firefox/comments/1sttf82/comment/oi1xklx/ this official comment). However, there are plenty of advanced ad-blocking extensions for Firefox.

Regarding your initial issue, an ad blocker might be the reason (and you can check that by temporarily disabling it), but you may also want to take a look at other standard troubleshooting steps that may help:

1. Please check if you have Enhanced Tracking Protection (ETP) enabled. You can do that by clicking the shield icon in the left part of the address bar.
   • If ETP is enabled, try disabling it.
2. If the problem is not fixed, try clearing Firefox cache.
3. If it does not help, try clearing cookies and data for YouTube (warning: you will be logged out on this website).
4. If it also does not help, try running Firefox in Troubleshoot Mode (which will, particularly, temporarily disable your add-ons). If the problem doesn't persist, please follow the steps from this article to troubleshoot further.
