Hi to all,
I've just wanted to make you aware that a new Firefox extension is available to help user opening files online: its name is Open IT Online. It supports several type of files (*.doc, *.rtf, *.odt, *.sxw, *.xls, *.csv, *.ods, *.sxc, *.ppt, *.pps, *.odp, *.sxi). It also allows you to choose which online service to use among Zoho Viewer, Google Docs and ThinkFree.
For the moment, this extension is in the Mozilla Update sandbox and hence it needs your good review to be promoted on the public section of the site.
