Fast market selling alone makes it great, not to forget about lowest recorded price and link to PCGW on store pages

Latest version on Firefox gives an error. "Failed to load your games. JSON.parse: unexpected character at line 1 column 1 of the JSON data
If you use Firefox containers, extension is not compatible with it."

Please add a support for Firefox Container.

Now scammy devs can't fool you with their "15quadrillion players play mah gam" bullshit, because this addon allows you to see exactly how many people played their shitty game. And that's of course on top of all the other useful additions, like quick sell. So yeah, a must-have for any frequent steam user.

amazing, makes steam so much better

Amazin extension if you use Steam. You can quickly see if a game sale is screwing you over by price history. Amazing stuff. Love it.
