I have seen this question asked and archived many times. I am in level III support professional and at home I have a Minnicks machine with Firefox to do what little surfing I do in my off time. All of a sudden without rhyme or reason I’m getting bad certificate notices and unsafe site notices for widely widely used sites. All the previous archived answers are very very vague & sometimes even condescending. this is the beginning of September 2020 in the forums are full of people complaining about it but apparently you see no reason to address it. Quit blaming the user. There is definitely something up I didn’t change any settings and I did not change my surfing habits and I didn’t download anything shaky. Whether you answer this or not is now academic because the way your previous answers were worded I have no intention of using Firefox again. And I’ve used it for many many years.

We don't blame any user for problems. We address the problems we hear about.

Are you using your employer's computer or their web-access? Is this your own computer at home?

What are the exact error messages you are seeing?


There is security software like Avast, Kaspersky, BitDefender and ESET that intercept secure connection certificates and send their own.
