Siphon is an extension for Firefox that allows you to synchronize the applications you choose to have installed on Firefox among multiple computers, this is similar to what extent has the new official Firefox called Sync Firefox can also synchronize the extensions between browsers. But to some extent Siphon is superior because it has the ability to choose which are the extensions that are installed and what not, through a management interface very easy to use.
This is a very useful extension for those with multiple computers with Firefox installed, or network administrators who want to control which extensions must be installed browsers on your network and thus ensure that employees of a company has all the tools they need to install in their browsers. but it can not synchronize the preferences of each extension.
Siphon is an add-on that works with Firefox 3.0 to 3.6 (not compatible with Firefox 4 beta yet).
