Developed by Zhenyi Tan, Vinegar is a universal extension for Safari that will work across mobile devices and Mac computers. However, it is an extension for the browser which means that if you want to take full advantage of it, you’ll have to watch YouTube through Safari which isn’t always the greatest experience.
However, the extension does offer up picture-in-picture mode for YouTube in Safari, it also removes in-video ads, it keeps videos playing when you switch tabs, choose to have it stream audio-only so you can play audio in the background, and it also stops YouTube from tracking your pause/play activities.
This means that this extension is kind of like a multipurpose tool for blocking ads, maintaining some degree of privacy, and also offering up functionality. It isn’t free and it is priced at $1.99, but the good news is that it’s a one-time purchase and you can use it across your Apple devices.
