This "Untrusted Connection" is coming up when I try to access my on-line banking site which I use all the time. I also get a OpenDNS message about Phishing and I'm not sure why or what that is. The same thing is happening on my laptop which has Windows 7.
Check out why the site is untrusted (click "Technical Details to expand that section) and if this is caused by a missing intermediate certificate then see if you can install this intermediate certificate from another source.
You can retrieve the certificate and check details like who issued certificates and expiration dates of certificates.
Let Firefox retrieve the certificate: "Add Exception" -> "Get Certificate".
You can see more Details like intermediate certificates that are used in the Details pane.
If "I Understand the Risks" is missing then this page may be opened in an (i)frame and in that case try the right-click context menu and use "This Frame: Open Frame in New Tab".
Note that some firewalls monitor secure (https) connections and send their own certificate instead of the website's certificate.
what is the exact message by opendns about phishing? you shouldn't take that lightly, especially when it's related to online banking, since phishing is a form of fraud to get to your account data...
An attacker can be trying to get your information.
Is good for you to scan your computer with an antivirus and check your wifi.
The error message may be caused by a MiTM attack or phising.
A little over my head. I completely uninstalled Firefox and installed a new version............the same problem. I have checked my computer for malware and viruses and its clean. Whats up with this?????
Hi kc2ifr, since you're new to this thread, can you describe whether this problem affects all secure sites for you, or only particular sites?
When you get the error page, if you expand the Technical Details section, what explanation do you see there?
Do you use either Bitdefender or Eset as your security software?
The problem started this am when I went to a web site and got all kinds of messages from my virus program (eset). I actually had problems leaving the site. Well,now it doesn't like facebook, twitter, this site and a few others. When facebook does launch, all it has is text in blue letters on the left side of the screen....no pictures. In twitter, this is what I get.. This Connection is Untrusted
You have asked Firefox to connect
securely to twitter.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.
An then.........get me out of here!!!!! These are the details...
twitter.com uses an invalid security certificate.
The certificate is not trusted because no issuer chain was provided.
(Error code: sec_error_unknown_issuer)
If ya need more info, let me know.
When you have a problem with one particular site, a good "first thing to try" is clearing your Firefox cache and deleting your saved cookies for the site.
(1) Bypass Firefox's Cache
Use Ctrl+Shift+r to reload the page fresh from the server.
Alternately, you also can clear Firefox's cache completely using:
orange Firefox button (or Tools menu) > Options > Advanced
On the Network mini-tab > Cached Web Content : "Clear Now"
If you have a large hard drive, this might take a few minutes.
(2) Remove the site's cookies (save any pending work first). While viewing a page on the site:
In the dialog that opens, you can remove your Facebook cookies individually.
Then try reloading the page. Does that help?
For anyone who needs it, here is a section from the ESET manual:
For SSL communication to work properly in your browsers/email clients, it is essential that the root certificate for ESET be added to the list of known root certificates (publishers). Therefore, the Add the root certificate to known browsers option should be enabled. Select this option to automatically add the ESET root certificate to the known browsers (e.g. Opera, Firefox). For browsers using the system certification store, the certificate is added automatically (e.g. Internet Explorer). To apply the certificate to unsupported browsers, click View Certificate > Details > Copy to File... and then manually import it into the browser.
I haven't tried that myself. You may need to close Firefox before trying to built-in option to add the certificate.
Did this and it now works.........and I was blaming firefox!!!!! ESET: setup -> advanced setup -> extend web and email tree -> SSL • SSL protocol: Do not scan SSL protocol
