Suddenly. Firefox won't let me go on the www

[Goldfynche]

Quite suddenly. Right out of the blue. Firefox bars me from going to any websites. Even this forum! I'd already been using the computer for a couple of hours! Will that be because I don't have any anti-virus software on my laptop atm?
I've had to go back onto the Win 10 PC in the mean time!

OK. Panic over! Somehow the date & time setting had got altered and Firefox objected to the wrong month showing. Everything was fine again as soon as it was correctly reset.

So right, and I would add a firewall as well...at least a software firewall, but additional NAT & SPI (hardware) firewall is even better.
