Live Query can fetch a full list of Chrome Extensions on a daily basis to help you inventory out-of-date or malicious add-ons.
Using this query, it is probably more interesting to look at the less popular extensions that appear on only a few endpoints.
Note: Due to the 10,000 result limit per query, you might want to tune your Live Query SQL to filter out known-good extensions.
