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 all,

while playing (or better "fighting"...) with a linux docker container on Win10/WSL2/Ubuntu for using the MS spfx tool chain, I generated a SEC_ERROR_REUSED_ISSUER_AND_SERIAL in FF85.0/Win10 by first setting up a certificate exception for a dev-cert (https://localhost:4321) and then have the certificate re-created.

As described the support article [https://support.mozilla.org/en-US/kb/Certificate-contains-the-same-serial...], I removed all certificate exceptions for localhost:* and deleted the "gulp" authority in options/security/certificates.

Unfortunately, the SEC_ERROR_REUSED_ISSUER_AND_SERIAL persists even after a restart of firefox.

Any help is very much appreciated...

Thanks & greetings Markus Fehn

Edited to add TLDR: some Firefox requests to Google servers seem to fail internally. What can I try to diagnose the problem?

I'm having a recurring problem with Firefox on various Google sites: google.com, Gmail, Calendar, Keep etc. For long periods of time (but not always), Firefox completely fails to load the site, or loses its connection after the page is loaded (for example Gmail displays an error message "Oops... The system encountered a problem (#001)"). The problem usually seems to occur for periods of many minutes, with occasional gaps where the sites work properly. Also, it seems to be site-specific: sometimes it will load google.com normally while Gmail is still having problems. This is really frustrating, I'd like to use Firefox for all my browsing but I also need to use Google services regularly and that doesn't work if Firefox won't load them properly most of the time.

I'm pretty confident it's a problem with Firefox itself, and not with my network or computer, because I get the same issue across multiple Firefox installations and versions (Firefox 90 and 91 on Windows 10, and Firefox 78.10.0esr and 90 on Linux), and while the problem is happening I can access the same sites successfully from a different browser on the same computer (Chrome or Edge). I've tried refreshing my Firefox profile, working in a private browsing window and using a completely new profile, but the problem still occurs. I've also made sure I'm using "Standard" protection in Firefox's security settings and disabled Enhanced Tracking Protection for the sites I'm trying to access.

I've tried to look at what's going on using Firefox's Network Monitor, and the key thing that seems to happen when this problem occurs is that one or more network requests to a google address (google.com, mail.google.com or ssl.gstatic.com) appear with "0 B" in both the Transferred and Size columns (see screenshot attached). Sometimes the failed network request has a simple padlock icon as in the screenshot, and sometimes a red error symbol with mouseover text that says a security error prevented the resource being loaded. There's also occasionally an error message in the Console: "A ServiceWorker passed a promise to FetchEvent.respondWith() that rejected with 'TypeError: NetworkError when attempting to fetch resource.'.". Removing the relevant service workers in about:serviceworkers doesn't make any difference. On Linux, I've tried using tcpdump to check the actual network traffic and it looks like nothing is actually sent across the network for these requests, so whatever the problem is seems to be happening inside Firefox itself.

Ticking the "Disable Cache" box in the network monitor doesn't help. If I manually resend the same request using the menu in the network monitor, a normal response is received (but the content is not actually displayed in the browser).

It looks to me like some kind of caching or security problem, where Firefox somehow gets in a state where some network requests are blocked or fail to load from a cache, but after a while whatever is causing the problem is cleared and it works normally for a minute or two before the problem recurs. I would simply report this as a bug on Bugzilla, but I can't offer steps for anyone else to reproduce the problem because it only happens when I'm logged into my own Google account. I've run out of ideas for how to diagnose or fix this. Can someone suggest anything else I should try? Thanks!

I am unable to connect to the Nord VPN website or the Express VPN website because of a security issue with the Firefox Browser and I am unable to bypass the security and go to the site anyway. Here is what the message said: Did Not Connect: Potential Security Issue

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

What can you do about it?

www.nordvpn.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.

How can I connect to these websites?

Firefox giving following error,

Websites prove their identity via certificates. Firefox does not trust this site because it uses a certificate that is not valid for 192.168.1.100. The certificate is only valid for the following names: anishamsi.lan:6659, 192.168.1.100:6659, 192.168.1.100, anishamsi.lan

I can see the url is there as listed by firefox error itself (verify with screenshot 1), the url is "https://192.168.1.100/api/validateLogin"

please see the screenshot as well. First screenshot is for the error, second is for the certificate returned by the website and as shown by firefox.

What is the error, i have created the certificate correctly. i am sure this is a bug in firefox?? If not!!! how u suggest i fix this i have added following alt names inside my csr. DNS.1 =anishamsi.lan:6659 DNS.2 =192.168.1.100:6659 DNS.3 =192.168.1.100 I have already uploaded the certificate at names screenshot.

Cannot bypass "Secure Connection Failed" when access an internal corporate device

Hi, We currently connect to a vendor devices admin page that is inaccessible via Firefox because of the following error "Secure Connection Failed" (Error code: SEC_ERROR_INADEQUATE_KEY_USAGE) and won't present the option to proceed via the "Advanced" option. Long story.... The vendor is aware of the issue and as the configuration page is always accessed internally and uses TLS in some form they do not want to allow us to make any changes to uploading our own certs.

Anyway recently I was made aware of a keyboard shortcut to force firefox to bypass the error screen and force a connection, however I have not been able to find it since on the Shortcut guide for firefox. Can anyone provide me with this shortcut, It will save having to switch between multiple browsers.

Thanks is Advance,

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.
