I was so scared I couldn't get a good wallpaper extension on firefox but this is literally perfect!

As someone with ADHD, I find I am way more motivated to use a product when it is decorated or visually interesting. Thank you! My calendar looks beautiful and usable now! Many thanks.

Is GCal Background 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.

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

Risk impact analysis details

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.

GCal Background is probably trust-worthy. Prefer other publishers if available. Exercise caution when installing this add-on.
