Please "copy" Opera's 'Easy Files' feature?

[burrery]

It's by far my favourite thing about any web browser and this single handed feature--if firefox had it--would convince me and probably my family to instantly switch! Being able to right click an image to copy and then have it basically temporarily stored as a file to *upload* is suchhh a life saving feature and I wish more browsers had this! 

I really, really, hope you think about mimicing this!
