## Description

Check file hashes (sha256) with VirusTotal - no file uploads, no telemetry. 

<strong>Faster checks</strong> because no file upload is required

The purpose of this extension is to make sure <strong>NO SENSITIVE DATA</strong> is being uploaded to <a href="https://prod.outgoing.prod.webservices.mozgcp.net/v1/3c6270adea6be05340ff3a367914237fe17625a56b414c607b6ac90a3cdcbffa/http%3A//virustotal.com" rel="nofollow">virustotal.com</a> 

<strong>Autochecks</strong> downloaded files. (experimental, expect inconsistencies). So far if the file is small or is downloaded immediately, this autocheck works fine. 

Otherwise, you can drag and drop the file from the downloads icon into "Upload and Scan File"

<code>Requires a VirusTotal API key.
