Open With Photoshop is a Firefox extension designed specifically for web and graphic designers, facilitating a seamless workflow between web images and Adobe Photoshop. Once installed, users can right-click any image on a webpage and select the 'Open With Photoshop' option from the context menu. This action triggers Photoshop to launch if it isn't already open, and the selected image is directly placed within the application. If Photoshop is running, the image is added to a new window instantly, enhancing productivity and efficiency in the design process.

This add-on also addresses common issues like the PNG transparency copy problem, making it an essential tool for designers who frequently work with web images. While Mac users may experience a slight delay when launching Photoshop, this is a known behavior of the Mac OS X environment rather than the extension itself. Overall, Open With Photoshop is a practical solution for anyone looking to streamline their image editing tasks.
