SEC_ERROR_BAD_SIGNATURE
I'm running version 58.0.2 (64 bit)
In the last couple of days I am unable to use Firefox. Every time I try to open a new web page I receive a SEC_ERROR_BAD_SIGNATURE.
I can't even get www.google.com to work! I get the same error. Pages that are saved in the browser before two days ago open fine. But anything new will not open I get the same error.
I get the error for pages I know are secure eg: Pinterest, Facebook etc

There is security software like Avast, Kaspersky, BitDefender and ESET that intercept secure connections and send their own certificate.

I don't have any of those on my pc.
Hi, Please : uninstall Firefox. Then Delete the Mozilla Firefox Folders in C:\Program Files and C:\Program Files(x86) Then restart system. Then run Windows Disk Cleanup. (Note: This should be Pinned and run Weekly, If never done below expect 10's of gig's) Then run it again and click the button that says Cleanup System Files. Note: your Firefox Profile is saved. But you should make a back up before you do :
