Firefox doesn't know about .url files. Those files are used by IE and won't work in Firefox, so Firefox either displays the file as a text file or offers to save the file to the hard drive.

If you want to open a link in Firefox then you would have to launch Firefox with the URL appended to its command line or append the URL to target field of the desktop shortcut.

Thank for your reply but that didn't answer my question. These links are Generated and we use several of them daily. They need to be launched by clicking on them. Not a command line. Not a new desktop shortcut. If Firefox can handle other files types like .PDF. Why can't it be told to open the .url file as a web address? so basically the only option to use in Firefox would be to create hundreds of command line changed desktop shorts a day?

A .url file is a special file type created by Microsoft. Firefox is a multi platform application and doesn't support all platform specific files like a browser that is designed for that platform does.

Try to ask advice at the Stack Overflow forum site to see if they know of an alternative.
