Diễn đàn hỗ trợ Firefox

From my desktop, Firefox refuses to connect to Dropbox.com. I get alternating error messages: PR_END_OF_FILE_ERROR SSL_ERROR_RX_RECORD_TOO_LONG

I've disabled extensions, cleared cache and restarted. Nothing has helped.

I also have Firefox on my laptop and have no problems connecting to Dropbox.com

Help. Thanks.

I keep getting "Secure Connection failed" for a hour at a time whe trying to access Mail online. I am a commentster, and don thave Adblocking. It hsppens on busy sections of Mail online

Secure Connection FailedAn error occurred during a connection to nregade1.nic.in. Peer’s Certificate has been revoked.

Hi,

I work in a technical profession where we have large amounts of GUI-configurable equipment. Firefox was my go-to browser to configure and maintain this equipment. Up until today, when version 140 installed unexpectedly.

There is no https in this equipment, no certificates, no certificate server, no DNS. Just a LAN cable, peer to peer, to use the browser as a GUI to manage the equipment. There is no need for high level security either, since there is no internet.

Now how do I do this? In previous versions of Firefox it was possible to override the security warning and proceed anyway, which is what we did. Now we don't get the option to override, and it does not appear there is any way to change this behavior in the settings. This heavy handed nanny stuff does not sit well with me and it has made Firefox 140 essentially useless for my purposes. I've rolled back to a previous version of Firefox for now.

Wenn ich auf web.de gehe, kommt immer diese Nachricht:

Secure connection failed and Firefox did not connect.

Was kann ich tun?

Hi folks,

From time to time, the button "accept the risk and continue" for a selsigned certificate (= generated locally using openssl, mkcert tools, etc) appears and sometimes not.

When the button is not displayed, then we got as error "SEC_ERROR_UNKNOWN_ISSUER". My question is then: "When SEC_ERROR_UNKNOWN_ISSUER is returned for selsigned certificate or not ?" Is there a way to debug and got a more verbose message to troubleshoot ?

Many thanks

Did Not Connect: Potential Security Issue

Firefox detected an issue and did not continue to mmlsay.assam.gov.in. The website is either misconfigured or your computer clock is set to the wrong time.

It’s likely the website’s certificate is expired, which prevents Firefox from connecting securely.

What can you do about it?

mmlsay.assam.gov.in 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. You can notify the website’s administrator about the problem.

Please see below: for 2 instances that are occurring daily with firefox and should not be: firefox.exe attempted to establish a connection relying on an expired certificate to ads.mozilla.org

firefox.exe attempted to establish a connection relying on an expired certificate to ads.mozilla.org

It is a good thing that I have a good security system as Firefox is not doing its job. What is the problem? This is happening at least 60 to 100 times a day now. Kind Regards, Charlotte Sainz

You have not fixed the above where Firefox is attempting to connect to expired certificates!!!!!!! when putting the ads.mozilla.org in a tab it CRASHES...... You have a major security Breech taking place here. Please fix it with Humans and not AI responses.

Kind Regards, Charlotte

I want to connect to a server with a self signed certificate. I add it to the Certificate Manager under Servers but Firefox refuses to connect.

How do I connect to server with a self-signed certificate?

I am trying to log on to Gordon Bernard Calendar Co once there I am informed that it is an insecure web site. I have been there many times. The GB web person says the prob. is on my end. My computer is old and I have always used version 7.

I was on the krogerfeedback.com site. Got finished and then went to kroger.com to load coupons for Friday. The page came up and said no coupons found try again later. maybe 30 minutes later can get to the site at all. I get this:

Secure Connection Failed

An error occurred during a connection to www.kroger.com.

It is not my internet causing it. I have been on you tube watching news clips and written a gmail to my sister while waiting for them to clear the error.

I hope I don't have to call their 800 number and talk to their helpless desk.
