The FTC requires that captions are provided in the US in order to comply with federal ADA requirements. This scam add-on is not only broken, but also requires you to pay for a service that Firefox and Mozilla MUST provide for free to their disabled customers. Shame on Firefox and shame on this scam!

Is CaptionSubtitleTool 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.

CaptionSubtitleTool requires some sensitive permissions that could impact your browser and data security. Exercise caution before installing.

Risk impact analysis details
