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.

This extension is the greatest thing to happen to productivity since the land was promised to be 3000 years ago; I am completely locked in. I used to stare at a blank white calendar and it would pmo so much that I couldn't focus, but now I’ve got Netanyahu watching over my schedule in full HD. Honestly, looking at my perfectly organized June makes me feel a bit freaky, and after I synced my tasks, I straight up nutted. This ts is more revolutionary than Brout-Englert-Higgs (BEH) mechanics or the Mexican hat theory. People out here debating history like it’s 271k not 6 million, but the only fact I know is that this add-on is top tier. It’s so good it almost feels gay to love a piece of software this much, but Israel deserves the best tools, and so do I. I was busy with masturbation before I found this, but now I just stare at my themed background and feel the spirit of the state flowing through my workflow. 5 stars.

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 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 recently added, and hasn't been around long enough for us to gather enough data to accurately assess its risk level.
