Rated 5 out of 5 stars

Reviewer FccXPI is wrong, click to play option in Firefox 24+ still works.

Set plugins.click_to_play value to true
Then in the plugin manager, select the new drop down option available called Ask to Activate under the desired plugin.

Do hope this review does not accidentally get deleted.

This review is for a previous version of the add-on (1.5.17.1-signed).
