Many users who work in a web browser need to occasionally open another application on their computer system. Webmasters might need to use a screenshot taking tool or sftp client to manage their websites. Other users might want to launch a music player, news reader or email client. The usual way of accomplishing this is to go to the start menu or computer desktop and launch the application from there.
The Firefox add-on External Application Buttons mod changes this as it allows Firefox users to add software links right in the web browser. Using the add-on is unfortunately a bit complicated, at least at the beginning. There is no visual sign of the add-on after installation.
What the Firefox user needs to do is to right-click on empty space in the Firefox toolbar and select customize. There should be a new item called applications in there which has to be dragged to one of the Firefox toolbars. There is apparently no icon for that item which means that it will show up as blank space in the toolbar at first.
A right-click on that blank space will open a context menu with the option to add a button to the toolbar. This will open a file browser giving the user the option to select any executable file from the computer system. The icon of that software program will then be displayed in the location in the toolbar. It is possible to add multiple icons (one after the other) until all program icons that should be launched from within the Firefox web browser are displayed there.
A click on a software icon in the toolbar will launch the application on the computer system. The add-on is working with all Firefox 3.x versions and can be downloaded from the Mozilla website.
Update: Forgot to mention that some advanced properties become available after adding a link to the Firefox toolbar. It is for instance possible to change the icon size, create a keyboard shortcut or set arguments for the application launch.
Update 2: The add-on has been removed from the Mozilla Firefox add-on repository. There does not seem to be a comparable solution at this point in time.
