I cannot get match color to work at all by dragging and dropping an image. Nothing changes, etc. I can manually 'add' ML Match Color and the finder window pops open for me to select a pre existing image. But dragging and dropping from the web does not seem to work.

Are you able to use drag and drop at all in Pixelmator Pro? For example, to add images as new layers in a composition? Or to quickly export a layer out from the app as its own image? Also, when you drag and drop from the web, which browser do you use — Safari or something different?

Drag and drop yes - works dragging images open into the app or from the mac os x finder, etc. - using Firefox currently.

I tested this with Safari - works fine.
It appears to not work using Firefox

Ah, interesting, it looks like dragging and dropping images from Firefox doesn't work in macOS generally — when I try and drop something onto the desktop or into my Downloads folder, nothing happens. It looks like that's a Firefox bug, in which case, there isn't much we can do to fix it.

Makes sense! Thanks for helping me figuring it out!
