Analysis
mozilla.org's social meta tag setup passes every check we run. The required tags are present, the image is well-sized, and the title and description fit comfortably within Facebook's truncation limits. There's not much to improve here - this is a strong reference for anyone looking to optimize their own social previews.
What's working well: social share image found; title length is good (31 chars); description length is good (134 chars). 4 of the checks we run pass cleanly.
