Great app that provides easy access to claude while doing whatever else I am doing without having to swap tabs.

Great little extension, if you are using it the way that it is meant to be used! if you want a vulnerable AI browser, go install one. Pros might need a quick little ai query for something they are doing but don't want to eat up all the memory opening a full tab. This is a good option. I love the convenience of Gemini in the top right like that, but there is no opsec with that convenient little button. I do use it, but I know the difference.

Is Claude Sidebar 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.

Claude Sidebar does not require any sensitive permissions.

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.

Claude Sidebar may not be trust-worthy. Avoid installing if possible unless you really trust this publisher.
