Features & Capabilities

⚠️ Important: After installation, navigate to a regular website (not the addons.mozilla.org page or the Add-On Manager), then click the icon once and confirm the permission. If the error message persists, please restart your browser. I am VERY sorry but apparently this is the way it is supposed to work with Firefox 😔

Screenshot the current viewport, a selected area or a specific element on the page and inspect the color shades and approximate color names of the pixels.

Click on the extension icon for different methods of selecting pixels to inspect

User Reviews

Very helpful, I like that it shows the color name. I only wish it was 1-click (no need to select between viewport and other options).

An easy to use, actually helpful extension for the colorblind.

Is color helper 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.

color helper requires a few sensitive permissions. Exercise caution before installing.

Risk impact analysis details
  • Critical Allows access to all websites, posing a significant security risk as it can monitor and modify data from any visited site.
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.

color helper has earned a fairly good reputation and likely can be trusted.
