Features & Capabilities

🪲 Known bugs

  • On Fennec (Firefox for Android) pages sometimes refreshes and the model is gone Workaround: Go to the previous page and reload the model
  • Simplify setting often does not work properly (good news: you don't need it!) Simplify helper from Three.js seems a bit buggy: Small models tend to loose vertices, large models tend to simplify slowly and freeze the page

Is Fox 3D viewer 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.

Fox 3D viewer 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.

Fox 3D viewer is recently added, and hasn't been around long enough for us to gather enough data to accurately assess its risk level.
