Firefox has moved to a rapid release update cycle, with new versions being pushed out on highly accelerated schedules. Unfortunately, this can cause problems with a variety of web applications, including ANGEL. ITS recommends that users disable automatic updates to Firefox in order to assure compatibility with campus applications.

2. From the options window, Go to the "Advanced" tab. Under the advanced tab, go to the "Update" tab.
3. Un-check Firefox under "Automatically check for updates to:"
