Win10x64, Brave 0.18.14
Photoshop CC 2017.0.1
In Brave (and Chrome, makes sense), if I am viewing an image (URL ends in .jpg), I can drag and drop an image into my email client (Thunderbird) but not into Photoshop. Shields up/down do not affect this.
I am able to do this with Firefox, using the identical URL.
Don’t see this mentioned, looking for corroboration.
