User Reviews
Reviews show a generally positive, well-regarded extension that users rely on over years and appreciate ongoing improvements. However, recurring issues include disruptive automatic scrolling when activating the extension, occasional UI visibility and compatibility problems (especially with local pages), and a less-than-perfect pixel scaling that users must tweak manually. A few users note initial setup friction but still consider it a valuable tool when working toward pixel-perfect results. Pros
- Generally positive experience with the extension and ongoing improvements.
- Long-term reliability and high user satisfaction (used for years).
- Perceived usefulness and value of the tool for achieving pixel-perfect results.
Cons
- Unpredictable scrolling behavior when opening the extension, clicking the eye button, or loading pages with the plugin enabled.
- UI visibility/compatibility issues on some setups (GUI can be invisible or not show up, and issues on local file pages).
- Pixel scaling is off and requires manual adjustment (e.g., about 0.92) to get the correct size.
- Occasional usability friction, such as difficulties uploading a new screenshot or understanding certain features.

Overall pretty good add-on. Thank you for continuing to improve it!
Is there a way to adjust overlay position with keyboard arrows buttons without scrolling the page?

Is Pixel Perfect Pro 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.
Pixel Perfect Pro 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.
- High ******* ******* **** *** ****** ***** *** ***** ** ******* **** ********* ********* ** * *********** *****
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.
Pixel Perfect Pro is probably trust-worthy. Prefer other publishers if available. Exercise caution when installing this add-on.
