Steam HLTB от Shahor

Automatically displays HowLongToBeat completion times on Steam store pages. See Main Story, Main + Extra, and Completionist times at a glance without leaving Steam. Data is fetched directly from HowLongToBeat.com. No account required, no data collected.

In order to avoid any data collection and security limitations, this extension opens a tab temporarily when you are on the store to retrieve the data from HLTB.
