URL Checker

Scan and check URLs with VirusTotal directly from Firefox.

Important: URLs submitted through this extension are sent to VirusTotal and are subject to VirusTotal's policies. Do not submit sensitive or confidential URLs.

• URL Check: Paste a URL into the single-use URL Check tab and scan it with VirusTotal.
• Saved folders: Organize frequently scanned URLs into folders so they can be easily found and rescanned.
• Context menu: Right-click a page or link to quickly add it to a folder. The context menu supports two modes.
• Scan results: View the most recent scan result for individual and saved URLs and open the corresponding VirusTotal report.
• Search: Search saved URLs from the extension popup and quickly navigate to the folder containing the matching URL.
• Notifications: Receive progress and final-result notifications while scans are running, including OS-level notifications when the popup is closed or out of focus.
• Cached results: URLs with scan reports of less than 12 hours old will be returned quickly without waiting for a new scan.

When a URL needs to be rescanned, the extension checks for an updated result at 20-second intervals, up to 10 times. If the popup is open, progress is displayed through toast notifications. If the popup is closed or out of focus, OS-level notifications are used instead.

Toast notifications remain available when the popup is reopened so you can see that a scan is still in progress.

URLs with a suspicious or malicious result require confirmation before opening the corresponding page.

A VirusTotal API key is required to use the extension. The extension uses your own VirusTotal API key rather than providing a shared key. Your API key can be set in the settings page of the extension.

You can obtain a free VirusTotal API key from VirusTotal.
