Cannot access Google and most other sites using Firefox

[Orcs]

Hi All

When trying to use Fire fox to access Google I get a message " Your connection is not secure"

I have cleared the cache and all cookies.

I have uninstalled and reinstalled Firefox

I have McAfee Antivirus running and Malwarebytes full edition running

But still the same issue

Anyone else had this ?

Have you tried Internet Explorer?

Nope...But had a strange email from CGI-Mailer (Germany ?)  this afto'......They seem to know my name, addy and telephone number, so I assume they've nicked this from someone's PC or phone ?

Cheers - It's not my day with computers, it seems.

Doesn't sound desperate enough to try that yet!

That's a standard (Ed Uni) response as it is a fully recognised standard world wide and you may get a recognisable error message which might lead to the culprit.

yes Internet explorer and Chrome both work fine.

Interestingly I cannot get onto the Mozilla support page either.  Checked on the internet and no suggestions apart from what I have done.

Running Firefox 45.0.1 with no problems here.

Did the most recent update in case there was a glitch in that but (famous last words?) everything is OK.
