In our organization we are using a firewall which has an Intrusion Prevention System. The IPS has a certificate which must be imported into the browsers to be able to load SSL websites. This allows the IPS to inspect the contents of secure packets for any malware or viruses. The problem is this isn't working very well with Firefox. Most secure sites bring up one of the following errors:

Secure Connection Failed The connection to <website> was interrupted while the page was loading. The page you are trying to view cannot be shown because the authenticity of the received data could not be verified.

OR

Secure Connection Failed An error occurred during a connection to <website>. SSL peer rejected a handshake message for unacceptable content. (Error code: ssl_error_illegal_parameter_alert) The page you are trying to view cannot be shown because the authenticity of the received data could not be verified.

Does anyone have any suggestions on how to get Firefox to work in this environment?

I am running Windows 10 with Firefox 40.0.3. If any more information is needed, just ask.

I go to the SAP Support page and log in with my credentials. I then proceed to 'Simplify my Login.' When I click on 'Download and Install a Browser Certificate,' I receive a page saying there is an 'Authorization Error.' I had no issues with this using previous versions of Firefox. Any help would be greatly appreciated.

I get this message whenever I try to enter facebook: An error occurred during a connection to www.facebook.com. Peer received a valid certificate, but access was denied. (Error code: ssl_error_access_denied_alert)

I've tried a number of solutions including changing security.tls.version.max to 0.

Anyway to fix this other than formatting the whole drive (which seems a bit exaggerated)?

And many other URLs, including Mozilla (!), so Firefox 40+ does not work (and I had the same problem on 38.0.1). I am using Yosemite (OS 10.10.5) on a MacBook Pro, but I had this same problem using OS 10.7.5. This is the message I get:

"This Connection is Untrusted

"You have asked Firefox to connect securely to youtu.be, 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."

"Technical Details: "youtu.be uses an invalid security certificate. The certificate is not trusted because the issuer certificate is unknown. The server might not be sending the appropriate intermediate certificates. An additional root certificate may need to be imported. (Error code: sec_error_unknown_issuer)"

Sometimes I get a page, such as the mozilla.org page, which has no graphics and is in bare outline form.

Yahoo mail gives untrusted connection error

When I log into Yahoo mail on Firefox 40.0.3 (on Windows 7) on my company-supplied laptop, I get this message: "You have asked Firefox to connect securely to us-mg5.mail.yahoo.com, but we can't confirm that your connection is secure."

I cannot create an exception: "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."

The "technical details" section states: "us-mg5.mail.yahoo.com uses an invalid security certificate. The certificate is not trusted because the issuer certificate is unknown. The server might not be sending the appropriate intermediate certificates. An additional root certificate may need to be imported. (Error code: sec_error_unknown_issuer)"

This does not happen at home, so the company laptop has something to do with it, but, even on the company laptop I do not have this problem when using Chrome, so it's not that the company does not allow access to outside mail.

On Firefox, the problem is intermittent. Sometimes, there is no problem and everything works fine. Clearing history/cookies/cache and restarting does not fix the problem. It sometimes goes away on its own for a little while, but then returns.

I have searched every database I could for answers, but have found no solution yet. The computer clock is correct, I'm not using Avast, etc. (some of the other situations I've run across).

I hope that I can get this resolved, because I'd rather keep using FF, which I've used for years, than switch to Chrome.

Thanks for your help, in advance.

I'm using F-secure Freedom for my VPN. I noticed that Firefox (only Firefox) cannot connect to any httpS sites as it tells me the certificate for any site (Google for example) is invalid.

Changing the proxy settings within Firefox does not help. Doesn't matter if I use current, beta, or developer build either.

I'm trying to get to https://mail.gmail.com

And your program is completely blocking me. I can't even and go add an exception for the server because it says it can't find the certificate. I don't care if you can't find the certificate. I guess I'll IE or chrome for this. Unfortunate, Firefox used to be my favorite.

Personally, I much prefer how IE says, I can't validate the certificate, continue (not recommended) or leave the site. Your program only blocks and doesn't give an option to proceed. even with Fiddler installed I can't identify what site it's tryig to get the certificate from. So, your dialog is useless to me.

Also, other secure websites are giving me problems your program.

Your last to version updates have been horrible. I frequently click on wen pages in my favorites and immediately get "Page Can Not be Loaded". Your web browser did not do this before your last 2 or 3 browser updates. Can you please get this fixed ASAP.

I am a medical insurance biller. I downloaded Windows 8, and Mozilla Firefox so that I could use United Healthcare Authorizations because they stopped allowing use on Google Chrome. I tried to get on the site, and the message I received was:

"An error occurred during a connection to saml2.radiologynotifications.com. SSL received a weak ephemeral Diffie-Hellman key in Server Key Exchange handshake message. (Error code: ssl_error_weak_server_ephemeral_dh_key)

   The page you are trying to view cannot be shown because the authenticity of the received data could not be verified.
   Please contact the website owners to inform them of this problem."  

When I looked this up, it said that your site said this was a malicious site and blocked it. This is a secure site. And I need this site for my work. I have been doing this for 15 years, and If I cannot use this I will be forced to use another browser.

Can you please help me?

I got the "This Connection is Untrusted" error on a website I use daily. In the past, there have been 2 options at the bottom of the page -- "Get me out of here" and "I know the risk". Choosing "I know the risk" lets you access the sight, but it is no longer an option. How do I access sites with expired certificates? I need to work daily with several NYS websites that have expired certificates.
