If you use YouTube, you know there are several forms of advertisements.
- Ads on the screen
- Links to other videos (some related, some ads)
- Ads before the video
- Ads during the video
You may also notice a black error screen that lasts a few seconds before your video starts playing. That error is because your ad blocker extension (STANDS fair ad blocker) is blocking this ad, but it can't skip the ad video, it just hides it from you.
One way to avoid see ads is to view the YouTube video in a program called VLC media player. VLC will allow you to watch the video and even download the video in many cases. See the article How to Watch a YouTube Video with VLC for instructions to watch or download videos.
