Firefox not loading on Windows 8.1 laptop

[techmot]

Recently, probably since I removed my laptops battery, I have noticed that Mozilla Firefox won't load any page and displays "unsecure network" error. Firefox isn't my main browser as I use Opera (which does work), but as far as I'm aware I haven't changed any of the settings in my anti virus or firewall. I also noticed that Tor browser won't load either but was working not that long ago. For some reason my laptops clock is set to the wrong date and time, and I've never known my other laptop do this when I have removed the battery.

Anyone know what could be causing this?

You need to set the date to current or you will get that message,are you running the laptop on adapter power?
