Firefox 技術支援討論區

I have recently upgraded to windows 11. After this upgrade, I am facing connection issue in the firefox. Generally, I keep open my Office Gmail Account till my office hours around 8 hrs daily. After the opening the mail it runs as usual, but after ten to fifteen minutes it shows connection error. It continues showing the same error for the whole day. While I tried this things with the other websites, it shows same error for other websites also. The same thing I have tried in Google Chrome browser, there is no such kind of errors or difficulties are found. Kindly guide me further or please update the same.

In the past it was possible.

How can I download a certificate from a web site?

I click in the Lock Icon in the url bar->...->..> View Certificate

It only shows a partial view of the certificate and there isn't a button for download the certificate.

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.

I have tried resetting my preferences to allow access. I can open my site in other browsers without a problem but really need to have clients access it from Firefox as well.

Please, please advise.

Thank you for your help!! Here is the error message:

when trying to access my website Noblittoilandgas.com I get a SECURE CONNECTION FAILED notice, Error Code: SEC_ERROR_REVOKED_CERTIFICATE, how do I fix this issue?

Have been trying to fix this problem - FF works beautifully if Kaspersky Internet Security is OFF but cannot access any websites when it is ON - just this PR_CONNECT_RESET_ERROR page.

Kaspersky support has been assisting but no solutions as yet. Any help from Mozilla is appreciated. This has been going on for 4 days now.

Using FF version 94.0.2 (64-bit) on Windows 10.

I've tried debugging the extension, errors in attachment

Why does this url fail? This is not the first url I have had that failed using Firefox but works on Edge and IE. Most that fail seams to be political. Is there any censuring being done on Firefox? Thank You Jack

I recently updated the SSL certificate for my business. My Firefox browser indicates the certificate is "not secure." When I navigate to my website using Bing, the SSL certificate shows as being "secure." I'd like the SSL certificate to indicate it is secure using Firefox browsers. Is there something I can do so that when someone lands on my website using Firefox it will correctly show that it is a "secure" site?

Thank you.

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,

Greetings. I can't open most sites I usually visit (even google.com) via my Firefox 98.0a1. This happens since today. All error codes are SEC_ERROR_LIBRARY_FAILURE.

Tried to:

• Disable DNS-over-HTTPS.
• Disable HTTP/3.
• Disable proxy (never had it enabled anyway).
• Disable sending info to Firefox developers.
• Change settings of DNS-over-HTTPS.
• Restart the browser (after each action).

Nothing helps me... But I still can visit some websites, but most common resources are not working for me. Please help me because I can't use Microsoft Edge without getting mentally ill. :/

Hi,

Firefox is displaying this message: Did Not Connect: Potential Security Issue

Firefox detected a potential security threat and did not continue to l.mail.people.com because this website requires a secure connection

and does NOT let me continue... HOWEVER, if I copy n paste the URL (https://l.mail.people.com/rts/go2.aspx?h=16465956&tp=i-1NHD-9U-36Hb-1OjSfX9-Hv-5EjIU-1c-Xmrj-1OjOLzQ-l78hyiHVom-1J3ttn&x=6b160f0f640ceeb5fd6f8fe1a3284d4886844914%7c739139%7c20220211%7c021122%7c739139%7c79459191515) to a DIFFERENT browser, there are NO issues with it.

Why is Firefox complaining and how do I tell it to STOP?

Secure Connection Failed

An error occurred during a connection to 61.5.135.10:89. Peer using unsupported version of security protocol.

Error code: SSL_ERROR_UNSUPPORTED_VERSION

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

This website might not support the TLS 1.2 protocol, which is the minimum version supported by Firefox.

I am repeatedly getting the SECURE CONNECTION FAILED error only for Google-related sites like Youtube, Gmail and Google search. I've to then close Firefox and immediately open it again to see those sites again.

This is the Error: Secure Connection Failed An error occurred during a connection to www.google.com. SSL peer was not expecting a handshake message it received. Error code: SSL_ERROR_HANDSHAKE_UNEXPECTED_ALERT

&

"Secure Connection Failed An error occurred during a connection to www.youtube.com. PR_CONNECT_ABORTED_ERROR"

FYKI, the problem started occurring in November, 2021. It had never happened before. I repeat, this error is occuring only for Google-related sites, not for others.

What could be the problem? Please help!

I am getting a Secure Connection Failed error on every website I try to log into on my laptop. The issue is not occurring on my desktop or either of my iOS devices under the same login account. I have tried every "fix" I can find through the FAQ's and through online googling, nothing has worked. I don't have any conflicting apps or security features that I can find. I have tried purging the history/cookies, un-installing and re-installing. After a re-install the websites will work for about 5 minutes then I receive the same Error message. Please help!

from whatever reason can't go to Rockler.com on Firefox - bud can on other browsers?! An error occurred during a connection to www.rockler.com. PR_CONNECT_RESET_ERROR

Hello, I've been unable to access google mail/drive recently, w error code SEC_ERROR_UNKNOWN_ISSUER and certificate issuer CISCO. i don't have any antivirus software, I've tried resetting the proxy, clearing cache, reinstalling Firefox, nothing works. If this continues I'll have to definitely move to another browser - with which I have no problem accessing those sites... Help please? Thanks

I have been trying to get on the Malwarebytes website, but I keep getting;

Your connection is not secure

The owner of links.malwarebytes.com has configured their website improperly. To protect your information from being stolen, Firefox has not connected to this website.

links.malwarebytes.com uses an invalid security certificate. The certificate is only valid for the following names: *.fortinet.com, fortinet.com Error code: SSL_ERROR_BAD_CERT_DOMAIN

This happens with all of my web browsers. Is it safe to allow Fortinet ?

Hello,

yes I know that version 3.6.28 is quite outdated now :) What is 20 years comparing to life on earth.. :)

Thing is that I need exactly this version of firefox because only with this version important web project works and now it is impossible to connect to server because I think TLS 1.0 not supported on server any more and old firefox can not handle the new one (do not know for sure, this is my opinion). So now I have very serious problem as I can not use needed web resource and deadline is tomorrow :(

So questions as follows: 1. Is there a way to force to work firefox 3 with web address https://varzybos.bki.lt 2. Maybe I can use non https:// version if all certificates are turned off in some way ?

I tried to add exception, then tried to play with various config option, nothing helped. So at this moment I am desperate.

Thank you so much.
