xIFr is a Firefox browser extension for viewing EXIF, IPTC and XMP metadata in jpg image files. Launch it from the desktop browser's right-click context menu.
In principle xIFr is a "cross-browser compatible" webextension. While it currently ain't available via Chrome Web Store, it still works with Chrome/Chromium based browsers if you install the webextension directly from your local filesystem. There are however differences in functionality supported, and mostly limitations when using xIFr in Chrome/Chromium based browsers. So for now only "officially" available for Firefox.
To create a browser extension from this repository, simply create a zip-file with content of the WebExtension folder.
Because I felt other Exif readers annoyed me, or I felt they were missing something. It is probably a matter of personal preferences, but you should really check the "deep search" feature. It works sooo well - in my own very humble opinion :-)
Most other Exif viewers for Firefox only works if you can right-click directly on an html img element. But with "Deep Search" xIFr finds the image you want to see details about, no matter if it is below a layer or is defined as a background-image of another element. In 95% of the times, it just works as you expect. You won't even know if you were right-clicking directly on an img element or not. This is in my opinion the most important feature distinguishing xIFr from other Exif-viewers.
Also, with Deep Search you can avoid overlayered logos and icons. By shift-clicking when selecting xIFr in browser's context-menu, you will force xIFr to look for images larger than a specified size (The size is configurable).
Deep Search is supported in Firefox 63 or newer. You can get a little introduction to xIFr's features, including what Deep Search does, at www.rockland.dk/xIFr/start.
Some websites override the browser's default right-click context menu. But often you can just hold down the shift key while right-clicking, to get the browser's native context menu back - and thus launch xIFr...
Vital parts of xIFr, is inherited work by various people involved with development of wxIF (xIFr is a fork of wxIF) and FxIF. Without their work, xIFr wouldn't be.
Also thanks to crimx, and his "Get All Images in DOM" coding-post which was great help implementing the Deep Search feature.
Finally, to help make xIFr cross-browser compatible, browser-polyfill.js from Mozilla's webextension-polyfill project is used.
