Yontoo add-ons has been blocked for your protection.

Why was it blocked?

A large amount of add-ons developed by Yontoo are known to be silently installed and otherwise violate the Add-on Guidelines.

Who is affected?

All Firefox users who have one or more of these add-ons installed. If you wish to continue using any of these add-ons, they can be enabled in the Add-ons Manager.

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.
