Why was it blocked?

This add-on violates Mozilla's Add-on Policies.

This add-on violates Mozilla's policies as search functionality provided or loaded by the add-on must not collect search terms or intercept searches that are going to a third-party search provider. The add-on has repeatedly violated these terms despite Mozilla explicitly pointing them out.

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.
