I-Firefox Isithangami Sokwesekwa

Hi team,

In our company we use FF 52.9 ESR, we also have exceptions to configure everytime a new colleague wants to access our intranet. Is there a way to configure a customised cert_override.txt everytime a new profile in firefox is created ?

Thanks for your help,

Hello,

bellow ca and cert leads to the SEC_ERROR_BAD_DER error in Firefox. In Chrome it works ok. What is wrong?

Secure Connection Failed

An error occurred during a connection to www.google.com. Peer’s certificate has an invalid signature.

Some website are opening fine but some are not, showing Secure Connection Failed PR_END_OF_FILE_ERROR. Even Google, Youtube are also showing same error page. I have tried every probable solution from internet. Even I have tried to open browser in Linux system installed in my pc and found same issue. This problem is coming from few weeks, previously it was fully ok.

Please help me to rid out of this.

I recently updated Firefox to 78.0.2 running on Ubuntu 18.04. After the update, I could no longer access my website. I emptied all the cookies, cache, history files and everything else and I still couldn't access the site.

I then upgraded Ubuntu to 20.04 with a brand new install that came with the same version of Firefox. I still can't access my website.

On a second computer also running Firefox 78.0.2 on Ubuntu 18.04 I can access my website with no problems. I can also access the website using Google Chrome and from my cell phone and tablets.

The computer on which I can access my website has the website's certificate permanently stored and I can view it from the site's page info. On the problem computer, there is no certificate stored. When I try to get the certificate, it times out with a message "Unable to obtain identification status for this site". No error page pops up and no other information is available.

Can anyone help out here?

I'm trying to visit https://dictionary.cambridge.org/dict.../hello and have received the message "Secure Connection Failed - An error occurred during a connection to dictionary.cambridge.org. 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."

No error code is given. No Advanced button for bypassing is given.

I've tried to disable everything related with ocsp and it did not work.

I would like to ask whether there is a way to accept the risk and bypass the security check (instead of patching security holes here and there).

Thanks in advance.

After a successful 2-way TLS handshake, I was able to browse my website for 1-2 times, subsequent requests failed with the "Secure Connection Failed" message and there is no error code to understand what the error is. In Network tab, it showed that Firefox didn't send the request to the web server (request_not_make_to_webserver.png). In Console tab, there was a message of "This error page has no error code in its security info" (console_show_no_error_code_msg.png). There is no issue to connect to my website using Chrome.

Did anyone face this issue before? What could be the cause for such problem?

Thanks, Tuan

I keep getting SECURE CONNECTION FAILED trying to sign in to my Gmail Email account. It was fine yesterday. Everything else (websites etc) I can accesson Firefox Browser.

HOW CAN I SORT THIS?

I am running a 2008 Imac on OS 10.11.6, and using Firefox 77.0.1 (64 bit).

Much of my work is online with one website, which I log onto daily. Today, I was unable to login because I received a "Did Not Connect. Potential Security Issue." I restarted, made sure Firefox was up to date, etc. The problem repeated.

Then I tried the website in Chrome. I got the same thing. I tried it in Safari. I got the same thing.

I called the company and spoke with tech support. He was unable to recreate my problem on his PC or his Mac. He confirmed that there was no certificate issue at the company and that they were not getting any other similar complaints or problems.

I then tried it on a Mac running 10.15, and was able to access the website easily, with no error messages.

My question is: is the problem my computer, and not the browsers or connections? Is there anything I can do short of buying a new computer?

Thanks for the help. Greg

hi. can anybody explain me the message SEC_ERROR_UNKNOWN_ISSUER when i use connection inside my company

when i add site to exclusion does firefox continue to protect my connection to site by using TLS or firefox stop use TLS and passwords transmit openly?

it is important to understand to me have i install a valid certificate on all my equipment to protect my connection inside the company.

or just add site to exclusion , because i know that certificate have been generated randomly and my connection and passwords to equipment is still by protection TLS.

On saturday our global sertificate expired and we renewed it a bit late. Now Firefox users cant visit our site, seeing this error message.

   Secure Connection Failed. 
   Please contact the server administrator or email correspondent and give them the following information: Your certificate contains the same serial number as another certificate issued by the certificate authority. Please get a new certificate containing a unique serial number.

   The page you are trying to view cannot be shown because the authenticity of the received data could not be verified.

Unfortunately the only way to fix it we found is deleting the whole profile, deleting the sertificates themselves does not work for us. It is very difficult for our users to do it. Can you please help us with this problem?

Well i0ve been reading lot of thread that describes this error, and none of them have a clear solution, so, im navigating normally on firefox while i work and suddenly if i need to download something from shutter it throws me this error, sometimes when im on slack the files that are being uploadded doesnt show and if i try to upload it doesnt work... recently i tried to change my profile, using firefox on another pc in the exact moment as the error show up, and also downgrading the about_config security level, i tried enabling DNS over HTTP and nothing worked, apparently ewhen i close and restart firefox it works, but it will continue showing up randomly and its kinda frustatring, it also happens on edge at the same time but on chrome it works... and i REALLY dont want to change from firefox to another browser... i really love this....

I am trying to get Firefox to load client certificates from a user's MacOS login keychain to support Mutual TLS. According to this Mozilla Security blog post I *should* be able to set 'security.osclientcerts.autoload' to 'true' in Firefox 75 or later, but I have not been able to make this work.

I am testing this on MacOS 10.15.5 Beta, with Firefox 76.0.1 (64-bit). I have imported a client certificate into my user's login keychain, and have confirmed that I can access a website that requires client certificates using Safari and that certificate.

I have set 'security.osclientcerts.autoload' to 'true' in my browser's configuration preferences, but when I attempt to browse to the website the connection fails with 'SSL_ERROR_HANDSHAKE_FAILURE_ALERT'. I have also tried creating a 'user.js' preferences file, but it did not help:

% cat user.js user_pref("security.default_personal_cert", "Select Automatically");

I very much need to make this work, and would appreciate any information about other configuration steps I need to take, or things I have missed.

Learn more…My Firefox is version 76 on Windows 10. Could you help please?

A webpage on our internal company domain ("") errors out with "Error SSL_ERROR_RX_RECORD_TOO_LONG". If I switch to private browsing the same page works. The page also works with all other browsers without issue. If I "reset firefox", the page starts working again - even after firefox sync has re-installed all my add-ons. After some indeterminate amount of time (weeks) the page starts to error out again. This problem occurs on Firefox 75 on Ubuntu 18.04 as of now.

I'm at a total loss as to how to even begin to debug this - any pointers on where to start looking? As I mentioned the webpage that errors out the only page on an intranet so I cannot share the URL.

Why does FF, since update 59, always freeze when I am trying to save web pages? Most times the download fails and I have to retry until it works. I can't use the browser until the download is complete. Sometimes the download is not the same as the web page. Looks totally different like a word document,
