Rated 5 out of 5 stars

For version 4.9.2, the preview may not render properly in Google due to the release of Google Instant Previews on Nov 9 2010.

The version 4.9.3, not yet approved by Mozilla, solves that problem.

This review is for a previous version of the add-on (4.9.2).  This user has a previous review of this add-on.
