I have been able to open the Hotmail.com calendar but starting yesterday it doesn't trust the certificate. I have another computer that it works fine on.

I have two computers running Firefox. one will let the hotmail calendar open but the other one gets the message that the certificate is not trusted and Firefox will not let it open. Both laptops are setup the same. I have checked the settings on both and they are the same. Not to be dramatic but my wife keeps all of her doctor and chemo appointments on that calendar and I would like to get it working.

Date / time correct in that PC?

yes, time and date are correct. Not sure why but this just started. to my knowledge, nothing has changed. it works on my computer, same as the other one. very confusing and frustrating.

Try to copy the file cert8.db from the working computer to the not working computer.

You can use this button to go to the Firefox profile folder:
