This is a plugin that automatically uploads to the server the images pasted from the clipboard with Firefox in CKEditor.

Extract the contents of the zip in you plugins directory, so it ends up like
this
ckeditor\ ... images\ lang\ plugins\ ... imagepaste\ plugin.js docs\ install.html ... skins\ themes\
Now add the plugin in your config.js or custom js configuration
file:
config.extraPlugins='imagepaste';
You have to configure the filebrowserImageUploadUrl entry as you might have already done to allow the user to upload images. You can get a simple script to use as a guide for your code in this post in my blog.
Using Firefox, paste an image into the body of CKEditor. That image will be uploaded to the server and it will use the correct URL instead of "data:".
