User Reviews

No hace lo que dice que hace. Instala otra extensión que en teoría hace otra cosa, y en la práctica no se ven los subtítulos en Youtube. Basura.

Is SubSync Master Safe?

Risk impact
Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

SubSync Master requires a lot of sensitive permissions. Exercise caution before installing.
