Besides looking through every one of your steam games, searching for a
specific game to see if you own it or not, there is no way of
determining if a bundle you're about to get on HumbleBundle.com has
games in your Steam library. Although it may be cheap, spending money on
a 10-game bundle where you already owned 9 of the games always makes me
frustrated, so I created this extension! This will gray-out any game you
own on Steam that is on any of the weekly bundles to let you know if you
own the game or not. It also has wishlist support to highlight games you
want on Steam!
How to Use
There will be a new extension icon in Chrome.
The extension might be hidden in the extensions menu, so you may
need to click the puzzle piece icon in the top right of your
browser to find it.
Click on that to input your SteamID or steam profile name (NOT
nickname) if you have that option set.
Click "Save" and you're done!
Notes
Make sure your profile is public, otherwise the extension will not be
able to access your library or wishlist.
Locate the large "... Account" text at the top of the page.
Find the numeric Steam ID below that (e.g. 123456#####654321).
Ensure you click the "ID64" checkbox after pasting your ID.
Game Names
Humble Bundle uses a different naming format than Steam does for some
games, but I will try to keep the alias file as up to date as possible
whenever new bundles come out or new games are added to a bundle. If you
see that games aren't showing up in a bundle, don't hesitate to contact
me!
