I've looked around at threads where other people had the same problem with Firefox blocking perfectly normal websites and the general answer seems to be to update my clock and reset the browser. My clock is not wrong, I have already reset the browser and yet the problem still persists. What do I do? The site in question is Facebook, more specifically just a dumb game on there with the certificate sco2-us.sng.ubi.com, which apparently is invalid. Any sort of fix would be appreciated, whether it be the problem itself or just turning off this extremely annoying "feature" of blocking sites.
