SmartUpscale - Enhance Image Quality on Firefox
SmartUpscale is a highly efficient Firefox extension designed to enhance the quality of images by eliminating blur when images are shown at integer zoom levels. Specifically useful for 4K or high-DPI monitor owners, the extension works by ensuring that images with an integer number of physical pixels larger than their natural size do not blur. It works once the page is fully loaded, after dynamic changes on the page, and on changing browser-level zoom. The extension's options also allow the limitation of the maximum image zoom where blur should be prevented and an option to disable blur globally if needed.
