Chrome extension by last updated time
Last updated time is updated whenever the developer releases a new version. Believe it or not, 64.09% of all items in Chrome Web Store have not been updated in the past 2 years. In the past 30 days, 4.61% of extensions have been updated.
An extension that has not been updated for a while may have been abandoned by the developer. As a result, any bug fix or new feature may never be made. This might be okay for some simple extensions that never really need to change, but other more sophisticated extensions will likely need more frequent updates.
