Sites Pro has been blocked for your protection.

Why was it blocked?

This add-on is silently installed into users' systems. It uses very unsafe practices to load its code, and leaks information of all web browsing activity. These are all violations of the Add-on Guidelines.

Who is affected?

All Firefox users who have this add-on installed.

What does this mean?

The problematic add-on or plugin will be automatically disabled and no longer usable.

When Mozilla becomes aware of add-ons, plugins, or other third-party software that seriously compromises Firefox security, stability, or performance and meets certain criteria, the software may be blocked from general use. For more information, please read this support article.
