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

Must have app!
