Nice little add-on Noté 5 sur 5 étoiles
I am a GUI guy: I know how to work from the command line, but I love to use the GUI features, particularly drag'n'drop for lot of tasks, from opening a file to moving text in my editor.
When I need to upload a file on a Web site, this little extension allows me to just select it in my Explorer (I tried it with Windows Explorer and Linux Dolphin), drag it and drop on the file upload component on the page.
There was a bug for some versions of Firefox, trying to drop two files at once, but since FF v.11, this has disappeared, perhaps it was a bug in Firefox after all...
A little add-on that doesn't do much, but does it well!
