xIFr - Getting started

xIFr is a browser extension to show EXIF, XMP and IPTC metadata in jpeg images.

After having installed it in your desktop browser, you can use this page as an introduction to features of xIFr, or to test it works as expected... The first three cases below may seem a bit boring, because even though they technically are very different, with xIFr you just do the same every time. But some of the cases have helpful tips for your daily use...

Users of older Firefox versions (or browser based upon that) might have to look in older versions of xIFr to find a version compatible with used browser. Latest feature-complete version of xIFr currently requires a pretty recent version of Firefox.

WARNING! There are currently a high number of unofficial copies of xIFr being posted on addons.mozilla.org, where they are presenting themselves with names like DataLens Pro Max, Photo Metadata Viewer, EXIF Inspector Pro, Image Insights+ and other variations. So far more than 35 "clones" has been found, and I'm busy trying to get Mozilla to delete them and stop the continuous flow of new copies being published. Note, under and after installation, these "clone extensions" all present themselves as "xIFr", not by the name they had on the installation page!

It is unclear what the purpose of these copies are. Maybe it is just to post spam-links (profile of uploader-account usually has a suspect homepage-link). Maybe the purpose is to sneak some malware into future updates?... So far the posted versions I have checked all looked like direct copies of xIFr version 2.12.0 (and thus still presents themself as "xIFr" and also comes with links to this intro-page included).

If you have installed one of these copies, I highly recommend you uninstall it immediately. Afterwards, hopefully you still want to give the original xIFr extension a try instead from addons.mozilla.org/addon/xifr/.

Basic functionality

Basic functionalty

The photo to the left is an image embedded the most simple and straight forward way you can do it (using the "<img>" html tag). To open xIFr and see metadata of the photo, right-click on the image and choose "View EXIF data" in the context menu...

Getting data from a background image

Deep Search

Photo to the right is not an ordinary html image element like above, but an image defined as a background style of another type of element. Many EXIF viewers cannot show you data for that. But with xIFr you usually don't care. Just right-click like before to open context menu and xIFr...

Getting data from an image behind a layer

Deep Search

The image to the left is sitting "behind" a layer. When right-clicking, you are clicking on a layer, not directly on the image. Some EXIF viewers cannot show you data for the image in such cases. But xIFr usually works fine. When right-clicking on [layer above] image, you can still select to open xIFr and see metadata of the image.

Notice, in a case like this (and cases like previous and next), you could say xIFr is kind of "guessing" which image you want to see data for, but it usually makes the right guess.

Ignore smaller images

Deep Search

Web-content can be constructed and layered in many different ways, and sometimes the "Deep Search" algorithm can get a bit confused. As in this case, where xIFr at first attempt probably will show you EXIF data for one of the smaller images even though you were trying to get data for the big image shown. But xIFr has a trick for such cases... Hold down the Shift-key while selecting "View EXIF data" in the context menu, and xIFr will ignore smaller images.

When is an image considered "small"? The default limit is 30.625 "squarepixels" (equivalent to for example 175x175 pixels), but it can be configured on xIFr's Options Page.

Prefer jpeg version when multiple formats are offered

Deep Search

Sometimes webpages makes images available in multiple image formats, letting the browser choose which format to display. With modern browsers, in most such cases, for example avif and webp images will be preferred over jpeg format images. Current version of xIFr can only parse meta-data from jpeg images, but xIFr will detect many of the cases where browser are presented with a choice, and try to find a variant of jpeg-format to parse and show meta-data from.

To the left you likely see an avif or a webp format image. However if you open xIFr on it, it should detect and parse meta-data from a similar jpeg variant of the photo.

Avoid right-click hijacking

Browser functionality

This is not really a feature of xIFr, but a little browser tip... On some webpages the browser's default right-click context-menu is overriden by other functionality or just blocked. But with Firefox there's a simple way you usually - or at least very often - can get it back. Just hold down the Shift-key while right-clicking on the image or page, and the browser's default context-menu should appear. Try right-clicking on the photo to the right - with and without holding the Shift-key...
