However, many report difficulties moving the chat overlay, particularly in fullscreen mode where it can get stuck or clipped. Some find that overlay settings persist undesirably after reinstalling.

Is Twitch Chat Overlay 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.

Twitch Chat Overlay requires a few sensitive permissions. Exercise caution before installing.
