Boxft: Box.net File Transfer
Boxft is a Firefox extension for file transfer to/from Box.net online storage. The front-end is based on the popular FireFTP extension. The back-end uses Box.net's APIs. If you do not already have a Box.net account, you can open a free account with 1GB online storage.
1. Basic operation:
Enter Box.net ID and password, and then click "Connect" to connect to Box.net. You can save the account info in Firefox by clicking "Save account". If you have used FireFTP before, you are already familiar with the user interface. See this GIF animation for a quick overview.
You may see a yellow bar that says "Firefox prevented this site (www.extensionholic.com) from asking you to install software on your computer". To allow the installation to go ahead, click the Edit options on the yellow bar, click Allow and Close. You then click the download link again.
