I know it looks legit — but this is a scam — don’t fall for it!
Look at the address it is coming from – it is NOT Mozilla.com. I’ve had several ‘attacks’ pop up this week – and simply go back a page, but that may not be the best idea – I don’t know. I have been scanning my system and nothing is found, so I’m feeling OK. Decided to install an adblocker today – one recommended in several Mozilla forums – so hope that will help. But wanted to let those who use FireFox browser know there is a false update being pushed by hackers.
