MOZILLA_PKIX_ERROR_MITM_DETECTED Error in every website, I use no anti-virus that could be causing this
I tried disabling windows firewall, refreshing firefox, uninstalling and installing again(EDIT: I forgot to mention but I also tried scanning for viruses using malwarebytes). It just doesn't open any website. Chrome works normally Heres one example of the crash messages:

That was it! Thanks a lot. I disabled the service and restarted the pc and it worked!
