Adguard Mac totally messes up Firefox Mac - HELP

I have had to install Firefox 61.0.1 to run a publishing system.

On my Mac Mini with no Adguard everything is fine

On my MacBook with AG 1.5.8 it blocks every website saying "Your Connection is Not Insecure" and insisting that totally valid site certificates are invalid. I can't even log into the Grammarly extension as the page is only partly functional.

Adguard does not show up in the browser window either

Whitelisting sites does not work

Extensive Googling has no answers


Cheers Robert

NOTE accurate path is from the Mac HD Library and not the User library, can be confusing
