Unfortunately, it's not working.

It's working, but not with all titles.

works ,good addon to see which games i already own in the steam library.

Unfortunately doesn't work. Installed, gave permissions to foxslash and humble, added icon to URL bar, clicked, set up vanity ID (64 bit ID didn't work at all), opened https://www.humblebundle.com/games/indie-houses-bundle?partner=tuxdb and neither Desert Child nor Hiveswap Friendsim are marked in any way even though I have both, I can see in console some time measurements, an object with my wishlist and list of games, then two empty arrays, no error.

Doesn't appearer to be working.

I don't think it works anymore.

Fast, does exactly what it says. Extremely helpful, saves me a lot of cross checking back and forth or copy-pasting my keys into Compare2steam. Also seamlessly integrates into the humble bundle website, which is nice.

Where has this been all my life?! 5 more stars! *****
