The Histogram Viewer generates the histogram of a selected image. When the user right clicks on an image, the option "Show Histogram of Image" is shown in the context menu. If the user selects this option a new window is opened which shows the histogram of the image.

I do a lot of photography, and Iook at a lot of other people's photographs. I think in terms of image histograms a lot, and being able to quickly glance at the histograms of pictures I'm viewing on line is VERY handy. This plugin does that excellently, I've used it for years and years now.

Is Histogram Viewer 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.

Histogram Viewer 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.

Histogram Viewer has earned a fairly good reputation and likely can be trusted.
