User Reviews

Extension is good, just a few bugs i noticed that i want to mention. Whenever a spell/trap card is played, there is no sound to it. (Is it intentional?) In Profile viewer you cannot see comments and friends. And when selecting Yes or no on "play with edisons pre erratas" I think there is no difference in card text? Is there a way to default to yes?

Is DuelingBook Overflow 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.

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

Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.
