How do I fix SEC_ERROR_LIBRARY_FAILURE?
I'm using Firefox Quantum and the day I installed it, everything was working great. But every since I've rebooted my PC, now I often get the error code SEC_ERROR_LIBRARY_FAILURE when I try to load pages, like Google. Please advise.

Could you try reinstalling the Beta?

If you haven't already switched from 32-bit Firefox to 64-bit Firefox, and you're considering it, please see this article first before doing that: How to switch from 32-bit to 64-bit Firefox. I just noticed the 64b, so never mind on the article.

What's your computer system and Firefox version?
There is security software like Avast, Kaspersky, BitDefender and ESET that intercept secure connections and send their own certificate.
