Google is now making it much easier to report "suspicious sites" in Chrome. Some of the sites you want to report include phishing sites, malware hosted sites, and similar harmful things. Google uses these reports to block websites for everyone.
This new official browser extension reports bad websites to Google Safe Browsing. This service is used by web browsers such as Google Chrome, Apple Safari, and Mozilla Firefox to proactively block malicious websites. When you visit a Web site, your web browser will check if it does not match a list of known sites that are known to be defective, and will issue a warning message. Think of it like antivirus software with definitions that block bad websites.
You can report malicious websites by visiting Google's "Report a phishing page" form and entering the address of the website. You can still do it ̵
Install the Suspicious Site Reporter from the Chrome Web Store. After installation, you can click the flag icon in your toolbar to report a broken website. The website and your IP address are required. However, you can also share a screenshot of the page, the DOM content (the entire HTML code of the site) and the recommendation chain (which shows how you got to the suspicious site).  Google can use these reports from Chrome users to proactively block these suspicious sites for everyone, making the Web a better place.
The company released this Chrome extension on June 18, 2019. This feature goes hand in hand with other enhancements against "deception" in Chrome, including warnings about confusing URLs like "go0ogle.com" in Chrome 75.
