What does it mean when I see "Connection Not Secure" on a website?
The “Not Secure” notification appears on all pages using the HTTP protocol, which is incapable of providing a secure connection. Historically, this has been the primary protocol used for the Internet.
Over the last few years, websites have been transitioning to HTTPS (note the S appended to the end) which does provide security.
The “Not Secure” notification does not indicate that your computer, or the site you are visiting, is affected by malware. It only serves to alert you that you do not have a secure connection with that page.
The classifieds site at RollaNet is currently not SSL enabled, which is why your browser is reporting the "Not Secure" notice. This is on our list to address at some point in the future, but we do not have a specific timetable for the change.
