You simply use the right-click menu when you have found a link that leads to a theme or plugin for WordPress that you want to install. Choose either to install a Theme or Plugin so that OneClick Installer places it in the correct directory. It works well with zipped plugins and themes which are automatically unzipped during the process.

The One Click Installer WordPress plugin needs to be activated first and both the plugins and themes folder needs a chmod of 755 so that the Firefox extension is able to place the files in the directories.

You would then install the Firefox extension and right-click a theme or plugin to place it in the corresponding folder of your WordPress blog. Plugin diagnostics tell you if everything is configured correctly which is a great way to check if everything is working correctly.

One Click Installer can be password protected to protect your WordPress plugins and themes from being overwritten by other users and offers a so called Purgatory which offers a secure way of deleting plugins and themes.

It can also backup your plugins and themes and store them locally as zip files for later usage. The author is currently developing a version that makes it possible to auto-activate those plugins and themes as well.
