Fireuploader

As of late, it has become more and more common to use file storing services that allow direct download. It is also very common that instead of sharing files using peer-to-peer to use sites like Rapidshare or uploading dozens of files to Facebook, and taking this into account, a plug-in like Fireuploader is perfect when it comes to uploading big file batches.

  Also known as Firefox Universal Uploader or Fire/Universal Uploader, this extension will allow us to connect with sites like Rapidshare.com, Photobucket, Mosso, Box.net, Flickr, Picasa, YouTube, Facebook, Webshots, Omnidrive, SmuMug, SmeStorage, Google Docs, Snaphappi, Adobe Share and Slideshare. Not all of them are direct download site, there are also photo and video sites. The important part to cover is to upload various files, some of which me be rather large.

  Fireuploader will let us simultaneously upload files to as many server as we want, and as many files as we choose, something that is generaly impossible and you have to upload one file at a time. Furthermore, the interface is very simple to understand (similar to an FTP client) and it provides us with lots of information that a lot of the compatible sites don't offer, like the amout of data uploaded or the amount of space we have left.

  It also has the option to configure premium accounts for those services that have this possibility.
