Would love to know this is being looked at for 56 as I doin't plan to move to 57 right away. I drag hundreds of images to various folders throughout the day and this is a problem. Thanks

Schwaggy, all I have been doing is highlighting a bunch, then right-clicking and telling Finder to "Rename" the file batch, adding .jpg to the end. I have to confirm each change, but it is much faster than manually re-adding the file extension one at a time. I am ready for the previous behavior to make a return though, it was so much simpler (and faster!) before.

Yes, thanks - I have been doing it with A Better Finder Rename but would obviously just like for it to work normally. BTW, you notice it's only jpegs? PNGs and other formats work fine for me.

Actually, I haven't noticed, as I work almost exclusively with JPEGs. To that end, I did just attempt a drag/save with a PNG, and it's exactly as you describe. I would love for the proper JPEG behavior to return.

This appears to be working normally again, for me at least. Very odd since there's been no FF update. I have 5 Macs and confirmed on all.

EDIT: and now the problem is back. I have no idea what's going on.

Unfortunately, I didn't think that the problem was fixed, schwaggy. I have been dragging images all morning, then saw your reply here. Sure enough, mine were still having issues.

I have basically the same issue as Zelf24. I’ve always been able to drag and drop a picture from Firefox on to my desktop and it saves as a jpg file or jpg type picture file and it would open in Apple Preview. I also have Adobe Photoshop on my Mac. For whatever reason that is now the default app that photos or photo related files open up in. I've done everything that I know of to change the default program from Photoshop to Apple Preview. I've done the Get Info, Open with Apple Preview. Then I would click change all. I've done this numerous times, to many times. Then for whatever reason if I drag and drop a website link onto my desktop the website icon has the @ symbol in it and says HTTP. It's @ HTTP like all my icons are generic icons and again this happened after the Firefox 56 update on October 4.

I have this problem also. I have found a SOLUTION that works. 1. Click on the file image on your desktop 2. Go to finder - click FILE 3. In file drop-down click on - OPEN WITH - choose FIREFOX A new Firefox window opens with the image. Drag the image to desktop and it will be visible showing thumbnail image like it did in the past. And you can view it in preview. Hope this helps.

Great workaround, AIKnow. It definitely works as you describe, although it is still unfortunately just a stopgap until the originally functionality is restored. Perhaps knowing this, the devs could be pointed in the right direction?

Also, it appears that your method appends the file extension on "drag to desktop" after opening in Firefox. That appears to be what creates the preview in Finder. Current native behavior doesn't append the file extension on the first "drag to desktop", and that is what creates the blank thumbnail preview, and inability to open in Preview.

Just wanted to note that this behavior is still present in Firefox 57.0.

Yes, it's a problem. But I am happy with the solution I have found in the meantime.

The workaround doesn't seem to work for me. Weird thing is that if I choose 'Open with' in Finder and select Firefox, it opens a separate instance of Firefox. If I choose to select more apps and then pick Firefox, it does open i the running Firefox instance. It doesn't change anything to the file however, and dragging it to desktop still shows no preview and extension.

seems to be a correlation, I have the same problem too and I don't have this behaviour with Chrome!

For those still following this issue, it appears that it was quietly fixed. All of my "drag to drop" images appear to be working correctly now. Can anyone else confirm in 58.0.1?
