Why did this happen?

This extension, theme, or plugin 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?

Until the violation is resolved, this add-on won't be available for download from addons.mozilla.org. It will be automatically disabled and no longer usable in Firefox.

How does Mozilla enforce its policies?

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