User Reviews

Users consistently praise BetterViewer’s zoom, rotate and in‑browser editing and call it a smooth, feature‑rich replacement for the built‑in viewer. Repeated complaints focus on recent updates that stopped it opening images by default, breakages in functionality (including the editor), and slow or absent developer fixes.

Pros

Powerful zoom and image tools (zoom, rotate, basic editing) praised by multiple users
Smooth, easy-to-use viewer that many say replaces or improves on the built‑in image viewer
Feature‑rich and reliable for desktop use—users repeatedly call it excellent or a 10/10

Cons

Recent updates removed its ability to open images by default (no longer the default viewer), which multiple users find disruptive
Reports of the extension or its editor not working recently—several users say it’s been broken for weeks/months
Perceived lack of developer responsiveness or timely updates to fix these issues

Recent reviews

Used to be a 5 / 5 extension, then after the v3 fiasco with Chrome, got updated for parity with the Chrome Exctension. It lost essentially all that made it worth using, just for it to be useless the same way in two browsers now. Also appears to be entirely abandoned by the developer. A real pity, it used to be an extension that I considered worth it to be included natively in Firefox

Doesn't work anymore since the update, so I'm changing my rating.

Is BetterViewer 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.

BetterViewer 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.

BetterViewer is probably trust-worthy. Prefer other publishers if available. Exercise caution when installing this add-on.
