Upload file from URL af goodthingscming

This extension will let you "fill" a file input directly from a URL. Normally, if you want to upload an image (or other file) from a URL, you first have to download it to your computer, then upload it, and then delete it from your computer.
With this extension, all you have to do is enter the URL of the file, and the extension will automatically upload it into the page for you.

You can use this extension to post an image on Facebook or Twitter, upload files to your Cloud storage, share a meme on 9gag or anywhere else you upload files.
