Features & Capabilities

Hover Zoom+ Official lets you enlarge images and videos by simply hovering over them on supported sites like Facebook and Amazon. The extension automatically scales media to full size while keeping it within the browser window.

This is an open-source version of the original HoverZoom. It focuses on privacy by removing spyware and not collecting usage data. It requests only the minimum permission to access data on all websites for image extraction, with optional permissions for history, downloads/saving images, or per-site configuration. If issues arise after site updates, please report them via the Support tab or the GitHub issues page.

User Reviews

Users generally find Hover Zoom+ useful and often works across many sites with a clean interface. When it functions, it receives positive feedback (e.g., stable performance on some updates, overall satisfaction). However, multiple reviews report recurring breakage after updates, with zoom and hotkeys not working. There are also complaints about missing or non-functional whitelist controls and some site-specific issues (like Twitch or XenForo). The main requests are stability, reliable keyboard shortcuts, and a functioning page-restriction feature to avoid broad page access.
Pros
  • Generally works well across most sites, with positive experiences when it functions.
  • Positive user sentiment when the add-on does work (e.g., 'latest version works great', 'simply love it').
  • Robust feature set when available, including image centering, hotkeys for saving, flipping/rotating, block list, and image locking.
  • Good interface and ease of use.
Cons
  • Frequent breakage after updates; the add-on becomes non-functional across sites (not working anymore).
  • Keyboard shortcuts/hotkeys sometimes fail or stop working.
  • Whitelist/exceptions management has disappeared or is hard to use; users want to restrict on which pages it runs.
  • Site-specific issues on certain sites (e.g., Twitch zoom loop, XenForo lightbox) that prevent zoom on those pages.
Recent reviews
Secretively reading data from almost all personal and shopping website and putting them in a kilometer long list under optional permission category. Very fishy.

It causes erratic behavior in the management of WordPress plugins. (enables or disables some plugins randomly, re-install removed ones, ...) Tested on several computers

Is Hover Zoom+ (Official) 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.

Hover Zoom+ (Official) requires a lot of sensitive permissions. 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 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.

Hover Zoom+ (Official) is probably trust-worthy. Prefer other publishers if available. Exercise caution when installing this add-on.
