Stopbleed is a free Chrome add-on developed by Tony Alves that helps users identify if the website they are browsing is affected by the Heartbleed bug. This add-on is an official mirror of the original Chromebleed Extension and comes with improved permissions. The code is open source, ensuring that no private information is accessed.

With Stopbleed, users receive a warning notification if the website they are visiting is vulnerable to the Heartbleed bug. This bug poses a significant threat to servers using OpenSSL, potentially compromising sensitive data. The extension checks the URL of the loaded page against a web service developed by Filippo Valsorda to determine if it is affected by Heartbleed.

In the latest version 2.2.3, Stopbleed has fixed notifications for Chrome 35.x and reduced the permissions required. Additionally, the search page injection feature has been deprecated, and users are encouraged to use Heartbleed Search for a better option with multiple search engines. The extension also updates the status icon on popup change, starts checking the URL once it is "loading," and updates the icon for the active tab.

It is important to note that site testing with Stopbleed and Chromebleed should only be done with the express permission of the site owner, as per the laws in your local area. Download this extension to protect yourself from the Heartbleed vulnerability and ensure the security of your browsing experience.
