You have asked Firefox to connect securely to www.gmail.com, but we can't confirm that your connection is secure.
Normally, when you try to connect securely, sites will present trusted identification to prove that you are going to the right place. However, this site's identity can't be verified. What Should I Do?
If you usually connect to this site without problems, this error could mean that someone is trying to impersonate the site, and you shouldn't continue.
This site uses HTTP Strict Transport Security (HSTS) to specify that Firefox only connect to it securely. As a result, it is not possible to add an exception for this certificate.
I have attached the screenshot, it does not allow me to add an exception. I am using Trend micro max security. When I try to log into http://www.ustream.tv/decoraheagles I get an error and it won't let me. I have tried every solution I could find in the community but nothing seems to fork. I can get to all my sites using IE10, IE8, Chrome, and Safarie, FF is the only browser I am having trouble with it started yesterday after upgrading to 43.0.3. When it started every site would give me the "This Connection is Untrusted" message but most of them allowed me to add an exception. What do I do about the ones that don't give me that option? They just say get me out of here. Fire Fox is my main browser, I sure don't want to abandon it. I also started FF without addons and that did not help also tried private browsing no help either

Thanks for the response. While I was waiting for an answer from anyone I continued to try to fix the problem myself. When I tried to open my yahoo page in microsoft edge it told me there was a problem with the proxy server. I went into settings and found that the proxy settings had changed from automatic to manual, I switched back to automatic and everything started to work.

Hi
A fix that may help with this issue has been released in Firefox 43.0.4. I recomend you update Firefox and see if the issue is repeated. You can read more about how to update here.
I hope this helps, but if not, please come back here and we can look into a different solution for you.
There is security software like Avast and Kaspersky and BitDefender and ESET that intercept secure connections and send their own certificate.

This Connection is Untrusted is sometimes caused because the computer system clock is wrong. Check the time / date / time zone settings.

That was very good work. Well Done. Please flag your last post as Solved Problem so others will know.
Any idea how it was changed?
