Dark Background Anti-Flash

Dark Background Anti-Flash reduces sudden white flashes on bright pages by using a temporary dark overlay that fades out smoothly. It does not override Firefox’s native New Tab page, and lets you tune page-load and tab-switch transition timing.

Is Dark Background Anti-Flash 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.

Dark Background Anti-Flash requires a few sensitive permissions. Exercise caution before installing.

Risk impact analysis details

Critical Allows access to all websites, posing a significant security risk as it can monitor and modify data from any visited site.

Risk likelihood

Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. 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.

Dark Background Anti-Flash is recently added, and hasn't been around long enough for us to gather enough data to accurately assess its risk level.
