i go to ladbrokes.com and get the following: Your connection is not secure

The owner of sports.ladbrokes.com has configured their website improperly. To protect your information from being stolen, Firefox has not connected to this website.

i hit advanced, but it will not let me "confirm exception" - except if leave out the www but even then when i confirm exception it still will not let me access the site - this is a new problem - i have been accessing the site for years with no problem...

I had no problem with the link.
