Features & Capabilities

Mocklet adds a panel to Firefox DevTools for turning recorded network traffic or imported HAR files into hosted HTTP mocks.

Record requests directly in DevTools or upload a HAR file, validate captured endpoints before deployment, tune matching rules for query parameters, headers, and body fields, filter entries by resource type, and create hosted mock servers with a configurable TTL. You can also review and delete mocks from the panel. A Mocklet sign-in is required.

Is Mocklet 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.

Mocklet 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.

Mocklet is recently added, and hasn't been around long enough for us to gather enough data to accurately assess its risk level.
