Features & Capabilities

Simple WCAG Contrast Checker helps developers, designers, QA teams, and accessibility reviewers find visible text on the current page that may not meet WCAG color contrast requirements.

Open the add-on on any supported http or https web page to scan visible text, highlight elements that fail the selected WCAG standard, and review a summary list of issues. Click a highlighted element or a summary item to inspect foreground and background colors, view the current ratio, and test alternate colors with a live editor and custom color picker.

Features include:

Automatic scan for visible text contrast failures
Switch between WCAG AA and AAA checking
Visual overlay highlights with ratio labels
Issues summary with click-to-inspect navigation
Live foreground and background color editor with custom color picker
Copy CSS selector for the selected element
Copy foreground or background hex values from the inspector
Rescan after page changes
Persistent panel state and layout preferences
Keyboard-friendly close with Esc

This add-on checks color contrast only. It does not certify full WCAG compliance, perform a full accessibility audit, or represent official W3C endorsement.

Is Simple WCAG Contrast 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.

Simple WCAG Contrast Checker 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 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.

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