Firefox: Your Connection Is Not Secure

A common problem I am learned. I looked into solving this while I decided to trial Windows 10 for two days and couldn't get to the bottom of it.

So after two days of spending all my time fixing bugs I decided to bin the whole idea and go back to Windows 7.

However, I seem to have brought back some of the bugs I was experiencing with me!

I might just do a system restore from a few weeks ago and that should solve any issues, unless someone has a better idea?

Maybe it's ESET that's causing the problem?

Anyway... Windows 10? What a disaster that is. I thought if I at least wait a while, I mean more than a year they'd have ironed out all the bugs by now, but apparently not. I'm about to give up on Microsoft forever.

On my way back I was asked for feedback. They suggested checking for updates. Or... they could just provide me with a fully updated and buig free OS in the first place!
