Browser extensions can do more than just block ads (amazing, I know). Take Enhanced Steam, an add-on for Chrome and Firefox, which tweaks the layout of Steam's online store to provide additional info about games and inject that data directly onto their individual product pages.
Once installed, Enhanced Steam makes browsing Valve's digital software catalogue a more informative affair. The extension's website has a laundry list of features, but here are the ones you'll want to know about:
- Highlights the games and downloadable content you already own
- Points out 3rd party DRM on games
- Adds DLC categories to the product page
- Finds out how much you really save on a bundle
- See pricing history for each game
- See how much you've spent on your Steam account
- Displays Metacritic user scores
- Gives you widescreen support information from WSGF
- Replaces the Steam Greenlight banner
That last feature I'm not particularly excited about, but that's probably because I have a game on Greenlight.
