User Reviews

User feedback is mixed but leans negative. The main issue is frequent non-functionality with skins stuck on Loading..., making the extension unreliable. A small number of reviewers did mention positive impressions ('really nice' / 'so good'), but reliability in Firefox is the major recurring concern across multiple reviews.

Pros

Some reviewers described the extension as 'really nice'.
Some reviewers described the extension as 'so good'.

Cons

Frequent non-functionality: skins stay on 'Loading...' or the extension stops working.
Firefox compatibility issues: reported not working in Firefox.

Recent reviews

For those that the Firefox extension doesn't work: is because the csfloat extension on here is the 5.11.0 and the actual one is the 5.14.0. Temporary you could use the Debugging feature of firefox to use the 5.14 version. Google "load temporary addon firefox manifest", download the "extension-v5.14.0-firefox.zip" from csfloat github (link on csfloat web) and follow the steps. this way doesn't updates the extension permanently, when you close the browser, the extension stays the same as before, maintaining the update from the firefox add-ons library when that happens.

It hasn't been working for a month now - all the skins are stuck on “Loading...”. It also crashes the Marketplace with a flood of requests that Steam flags as unwanted.

Is CSFloat Market Checker Safe?

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.

CSFloat Market Checker requires a few sensitive permissions. 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 Add-ons Store, 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.
