I always run FF in Private Browsing mode and never have it remember any logins or passwords. This issue confused me as it fails to load the site even when I gurgle for lottery and click the proffered link. I do have the lottery in a bookmark which equally fails to load.
Previous versions of Linux I have used (Ubuntu mostly) have completely failed to update to a later version when I have accepted the offer and have left the machine needing a complete wipe of the hard drive and a start over installation. I have not been tempted to up version the Cinamon until now.
I'll give the FF a new user profile first.
