User Reviews

User reviews show the add-on performs well on tricky sites and offers good customization and file-type recognition. However, reliability is inconsistent, with many reports of it not working on various sites or environments. Site compatibility often requires whitelisting or tweaks, and some sizing quirks or setup hurdles are common. When functional, it delivers centered, larger images and serves as a solid replacement for older zoom tools.

Pros

Works on tricky sites and galleries where other zoom tools fail (e.g., XenForo with broken lightbox).
Strong file type recognition and broader functionality, including handling webm formats and allowing saving through the hovered image.
Highly customizable and considered a good replacement for older zoom add-ons; offers more features.
When it works, it delivers centered, larger images and performs its intended zoom behavior.

Cons

Inconsistent and unreliable performance; multiple reviews report it doesn’t work on many sites or in some Firefox environments.
Site-specific compatibility issues; often requires whitelisting or tweaks to function.
Some images do not appear at the expected size; occasional sizing inconsistencies.
Setup can be non-intuitive and may require specific configuration (e.g., popup size) to function.

Set the pop up size to 50% otherwise it won't work. Offers invert black list. Images are centered and large enough. Works even on Xenforo galleries with broken lightbox, nice workaround, you can still right click and save "through" the hovered image. Thank you to the developer, don't change anything, except if you want to look at Hover Zoom! and implement all their features (action keys etc). But this add on right here has better file type recognition and thus wider functionality even with recognizing and filtering .webm(followed by numbers).

Is hooverZoom 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.

hooverZoom requires some sensitive permissions that could impact your browser and data security. Exercise caution before installing.

Risk impact analysis details

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.

hooverZoom may not be trust-worthy. Avoid installing if possible unless you really trust this publisher.
