Key master makes it easy to check game pricing without leaving the Steam store page. It provides a link to the relevant page on the G2Play, Kinguin and G2A key market platforms to make the transition easier between these stores. Just open a game on the Steam store, and after a second you'll notice the big yellow buttons underneath the Steam "add to cart" button!

FAQ:

-Are these sites trustworthy?

They are nothing but a digital distribution site for keys. If you have no concerns buying keys on Amazon, they shouldn't cause any worries.

-Could you implement "x" feature?

Send in your feature and I'll take a look at its feasability.

The prce shown on my steam store page is extremely high. How come?

This means that the price was correctly scraped for your own currency but the currency sign is wrong. My apologies. I did not foresee this. I will tackle this bug ASAP

Extension safety

Risk impact

Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Key Master requires some sensitive permissions that could impact your browser and data security. Exercise caution before installing.

Risk likelihood

Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Browser Add-ons, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.

Key Master is probably trust-worthy. Prefer other publishers if available. Exercise caution when installing this add-on.
