Do you use ESET security software? Its feature of scanning your SSL connections has been linked to this particular error code in the past. Do you want to try disabling SSL scanning in ESET and see whether that resolves it: http://kb.eset.com/esetkb/index?page=content&id=SOLN3126 If that works, there might be a problem of duplicate ESET certificates in Firefox's certificate store. It should be fixable.
There were recently several users getting this error code who use AVAST 2015. If you recently got that program, please see:
I was just struggling with the same issue. I do have Avast and found that it created this problem. I used the solution I found on: https://support.mozilla.org/en-US/questions/1028985
I disabled 'https scanning' in the Avast web shield settings. Since changing that setting, the problem has not recurred.
I will note that I have the same software installed on two computers, but the issue only occurred on one. So, there may be other contributing factors (OS, hardware, etc.) but the fix worked.
