PixelZoomer is a powerful Firefox extension designed for web developers who need pixel-perfect precision. It captures a screenshot of the current website and enables zooming up to 3200% without any anti-aliasing, ensuring crisp rendering of pixels. With PixelZoomer, developers can accurately measure distances between elements and pick colors using an integrated eye dropper that outputs HEX codes.

This tool simplifies the web development workflow by eliminating the need to export screenshots to external image editors for analysis. By analyzing sizes and distances directly in the browser, PixelZoomer streamlines design verification and pixel-level inspections. Since version 2.0.0, it supports Firefox's Electrolysis (e10s) as a WebExtension for enhanced compatibility and performance. For additional details and demonstrations, visiting the PixelZoomer website is recommended.

Extension safety

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.

PixelZoomer 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 Browser Add-ons, 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.

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