If you've recently upgraded Firefox, you may be receiving multiple popups regarding certificates. This is due to a change in Firefox's default behavior.
We've modified server settings to compensate, but you still may want to disable the certificate-related popups by modifying your Firefox preferences:
On a Mac:
go to Firefox -> Preferences -> Advanced -> Encryption
On Windows:
go to Tools -> Options -> Advanced -> Encryption
..then change from 'Ask me every time' to 'Select one automatically'
