Configure Firefox For Use With Court Audio Files

Instructions designed for Microsoft Windows 11 and Firefox Version 118.0.

Most browsers, when clicking on a PDF link, will open a PDF preview within the browser window. But if you need to download the PDF and not preview it, as is the case with court audio, you will need to change one setting in the browser. The key to listening to court audio is that the PDF must be downloaded to your computer and opened with Adobe Acrobat or Adobe Reader. Please ensure that Adobe Reader is currently installed on your computer before continuing.

Why can't I preview the audio in the browser?  Court audio is embedded wihin a PDF file and you will need Adobe Acrobat Reader® or Adobe Acrobat® to acesss the audio.
