Metrics.upload.enable

Background

Firefox 2.0 will include code to optionally record “browser metrics,” or usage statistics, and send the information back to Mozilla for analysis. The goal is that this information will aid developers in choosing features, designing UI behavior, identifying web sites that can cause problems, and other important points of the user experience.

This preference controls whether recorded metrics data are uploaded to the URI specified in metrics.upload.uri.

Possible values and their effects

True

Periodically send metrics data to the URI in metrics.upload.uri.

False

Do not send metrics data. (Default)

Caveats

• metrics.upload.uri must be non-empty and valid for this preference to have an effect.
