User Reviews

Users consistently praise Dezoomify for enabling access to full-resolution images and for saving manual effort when collecting artwork or archival imagery from online galleries. The extension is described as highly useful across a range of sites and workflows, often enabling tasks previously done by hand or with much more work. Some reviewers note reliability issues on certain sites or that the project is not actively maintained, which can be frustrating. Overall, the feedback centers on strong value and time savings, with occasional performance inconsistencies.

Pros

Saves a lot of time and reduces manual effort.
Extremely useful for archival imagery and museum-related content.
Widely praised as a practical, underrated tool.

Cons

Recent reviews

While at first it may not seem to work with an library or art gallery collections, you can often click through to an enlarged screen version of the work, and it will then be able to see it. I've found it works fine on several museum and art websites, enabling one to download public-domain images that should have been free to download already (by the taxpayers who've already paid for them).

This used to work very well, and might work for some websites, but for its advertised purpose of downloading artwork from museum digital galleries, it no longer works. I'm very disappointed that the developer is no longer maintaining it. I hope they come back and fix the issues soon.

Is Dezoomify 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.

Dezoomify requires a few sensitive permissions. 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.

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