What is A-B Loop?
A-B Loop is a Firefox add-on that lets you loop between any two points of an HTML video, making it convenient to repeat specific sections of a video, such as a YouTube video.
A-B Loop is risky to use as it requires a number of sensitive permissions that can potentially harm your browser and steal your data. Exercise caution when installing this add-on. Review carefully before installing. We recommend that you only install A-B Loop if you trust the publisher.
A-B Loop has earned a fairly good reputation and likely can be trusted.
