can't browse - insecure connection

I've just installed firefox on my iMac. Any attempt to browse anywhere bring up error message that the website is wrongly configured and therefore the connection is insecure - there is no option to proceed. This include mozilla website, google etc.

hello, first please make sure that the date, time & timezone are set correctly on your system. if this doesn't solve the issue (or it is already set properly), a solution depends on the individual circumstances:

  • what is the error code shown when you click on advanced on that error page?
  • please also give us more information about the error by clicking on the error code, copying the text to the clipboard and then pasting it here into a reply in the forum.

thank you!
