After the google outage a week ago I can't get into any google site. I asked a friend that also uses firefox and they can access them just fine, I can enter normally with other browsers, too.

Here's a transcript of the error page, if it helps:

Did Not Connect: Potential Security Issue

Firefox detected a potential security threat and did not continue to www.youtube.com because this website requires a secure connection.

What can you do about it?

www.youtube.com has a security policy called HTTP Strict Transport Security (HSTS), which means that Firefox can only connect to it securely. You can’t add an exception to visit this site.

The issue is most likely with the website, and there is nothing you can do to resolve it.

If you are on a corporate network or using anti-virus software, you can reach out to the support teams for assistance. You can also notify the website’s administrator about the problem.

After looking into it more, I found that I had the exact same problem (and solution) that this reddit post had 7 months ago.

The problem was fixed by turning off proxy.

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

Sorry, current forum security sometimes delays the posting of messages. And in turn, we are not notified of those posts.
