Sanity Check Firefox

Sanity Check

By: DBax Add-on
Analyze job ads against your skills and preferences, identify warning signs, and get a private, local second opinion before applying.

Features & Capabilities

Sanity Check is a privacy-first browser extension that helps job seekers evaluate job advertisements with clear eyes. Highlight a job description or paste it into the extension and receive an instant analysis based on your own preferences.

Configure the skills, technologies, keywords, and phrases you want to see, along with terms you'd rather avoid. Sanity Check provides:

• Match and mismatch scoring based on your chosen criteria • Detection of custom warning phrases and employer red flags • Plain-English explanations of phrases that may indicate unrealistic expectations, role scope inflation, social engineering, scams, or exploitative workplace practices • Fully local analysis with no accounts, no telemetry, and no external services • Customizable settings so you remain in control of the criteria used during evaluation

Unlike AI-powered services that send data to remote servers, Sanity Check performs all analysis directly within your browser. Your job searches, preferences, and assessments stay private. Whether you're reviewing a software engineering role, a data position, or any other opportunity, Sanity Check provides a calm second opinion before you invest your time in an application.

Is Sanity Check 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.

Sanity Check does not require any sensitive permissions.

Risk impact analysis details
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.

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