User Reviews

silly mode made my computer super laggy and I'm using i7 intel core. i have no idea how the silly mode works other than it crashing all my applications. I think there could also be a size function for the emoticons.

Is :3 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.

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