Suspicious Site Reporter is a free Chrome extension developed by Google that helps protect web users from suspicious sites. With over four billion devices protected every day, Google Safe Browsing detects and warns users about dangerous sites and malware threats. This extension allows users to report suspicious sites they encounter while browsing the web.

When you install the Suspicious Site Reporter extension, you'll notice an icon that appears when you visit a potentially suspicious site. By clicking on the icon, you can access additional information about the site, which can help you determine if it is indeed suspicious. If you believe the site poses a threat, you can click on "Send Report" to submit it to Google Safe Browsing for further evaluation.

Please note that if you're looking to display full URLs in the Chrome address bar, you no longer need this extension. Instead, simply right-click on the address bar and select "Always show full URLs" from the context menu.
