Steam Database for Chrome, Firefox, and Edge will add database links and features across the Steam Community/Store.
Not only will Steam Database do what is mentioned above, but it can also highlight owned and wished products on steamdb.info as well. It will give you more detailed info when you open a game page. Not only that, but it will also detail the lowest historical price, how many players are online, peak times, ratings, and it will let you know the date of the last update - not bad for a free/Open Source browser add-on/extension.
For a full listing of the numerous features, head over to the author's site.
