Doesn't work with Quantum Nightly. As others have said, simply downloads the file without opening in. Set Photoshop path correctly.

Please please fix this, it was such a great addon

Baris, please update this awesome extension.
Mozilla extension policy is completely disrespectful and subversive towards community and addon developers.

Don't work anymore

Sometimes it works then its super handy and awsome, but sometimes it doesn't work. Now it doesn't work since a half a year :( It only downloads the image but doesn't open it in photoshop. Please Fix this. I'm on High Sierra.

Regrettably, it no longer works with Firefox Quantum and/or new Photoshop CS2017 (v19)

FF 56.0, Windows 7. Just downloads image to downloads folder. Tried with OWP Communicator, but that didnt help.
UPDATE. Got it working again by downgrading FF to version 55.0.3 and downgraded "open with photoshop" to version 55.0 and It works again.
