Firefox might need to be set up to work with your security software if it intercepts secure connections for filtering purposes. Filtering involves showing Firefox a fake certificate so that the filtering software can read everything sent to and from the server. Programs that do that include avast! 2015, Kaspersky, ESET, and BitDefender. Do you have any of those?
