Features & Capabilities

Adjust Image Contrast lets you boost or soften contrast on any image right on the page you’re viewing—no upload, no download, no new tab.

Open the extension, click an image, and move the slider. Values above 100% increase punch; below 100% soften the look. Everything runs locally in your browser, so your photos never leave your device.

Why install it? Because sometimes you only need a quick look: Does this product shot need more punch? Is the photo too harsh? Will this thumbnail still read if contrast is lower? Instead of saving the file, opening an editor, and exporting again, you get an instant on-page preview in seconds.

How to use

Open the extension popup and click “Start Selecting”. Hover over images (dashed outline appears). Click an image to select it. Drag the contrast slider (0%–200%; 100% = original). Press Esc or close the panel to exit. Ideal for designers, marketers, content reviewers, and anyone who wants a fast contrast check while browsing—lightweight, private, and built for the moment you need it.

Is Adjust Image Contrast 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.

Adjust Image Contrast 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.

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