Avast Antivirus states this detects trojan horse Nostr.bitcoiner.social url and there's no such url I visit. Also this addon is hackable, can see all your site data, get your info leaked, it's a signer for Nostr sites like a public relay, it supposed to be private, but there's no guarantee, and it got flagged by avast which is telling, if you can talk to Avast about it can get it fixed, and also it's too risky to know all site data that could include payment info or login info even if it's encrpyted or disabled everywhere else. But if I can get some assurance and get the Avast team to fix this I'll rate higher

Is Nostr Connect 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.

Nostr Connect 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.

Nostr Connect has earned a fairly good reputation and likely can be trusted.
