• Improved performance when determining image type (raster or vector).
• Minor improvements.

* Better performance.
* The `box-sizing` CSS-property is now taken into account when determining image size.
* In Firefox for Android, processing is applied only to pages where it’s possible to determine the real screen pixel density.
* Adaptive images are now not processed since it’s technically impossible to determine their real size without reloading image file.
* Workaround for the bug 1275287 in Firefox 55 (Nightly) that caused wrong rendering of the user interface of the extension’s options.
* Dropped support for Firefox versions older than 52.

Changes since version 1.1.1:

* Each image is now processed immediately once it’s loaded, without waiting for other images to load.
* Improved detection of dynamic page changes. As a result, for example, enlarged screenshots of the pixel-art game Owlboy are now displayed without blur.
* Improved detection of integer image-zoom levels with accounting for specifics of floating-point numbers.
* Added extension icon.

Changes since version 1.0.3:

In Firefox for Android, determining image zoom now accounts for an additional Android-specific zoom as well as possible device-orientation changes.

Fixed: webpages’ own window-resize handlers did not work. (Turns out WebExtensions scripts are not quite isolated from web scripts.)
