Some forms on MyJudson require Adobe Reader DC or above to fill out. You can download Adobe Reader here. Instructions on installing are here for Windows and here for Mac. When completing the installation, allow the Chrome Extension to be installed, but turn off the extra software (i.e. McAfee). When you open your browser, it may ask if you want to enable the new Adobe Reader for the browser, say Yes.
You might need to tell the browser to open the PDF document in Adobe, as it may open in the browser's PDF viewer (the viewer will not allow you to submit a form over the internet). This is generally done in the right-hand upper window. There will be an "Open in Adobe" or "Open in another program" menu selection.
