I have a new microsoft Surface 6. Windows 10. Firefox security is too strong if I can't even access mozilla suport: https://support.mozilla.org/kb/what-does-your-connection-is-not-secure-mean. I can't access United airlines. Do I have to delete my account and reinstall.

When clicking on the "Automatically add" button below next to "troubleshooting information:" I am taking to a add-on screen that says "We're sorry, but we can't find what you're looking for"

Something is wrong with firefox.

I have windows 7 and firefox 63.0.1 and cannot get on google.com because of a security issue. The error is as follows:

www.google.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

I uninstall firefox and resinstall and it works fine for a short period of time. Then without warning, google no longer works and I get the security issue. I have uninstalled and reinstalled 4 times now and it is still doing the same thing. Works for a while and then not.

I also tried using version 62 of firefox but that also exhibited the same issue.

I researched this issues and there are all sorts of attempted fixes that supposedly get rid of this issue which I have attempted to no avail.

Will someone please help me understand how to fix this issue. I use google and gmail all the time and this is becoming a real issue. Your help is much appreciated.

Ever since I upgraded to Firefox 63, several trusted websites have stopped loading; instead I get sent to an error page with:

Your connection is not secure

The website tried to negotiate an inadequate level of security.

<www.thestar.com> uses security technology that is outdated and vulnerable to attack. An attacker could easily reveal information which you thought to be safe. The website administrator will need to fix the server first before you can visit the site.

Error code: NS_ERROR_NET_INADEQUATE_SECURITY


This also occurs with https://download-installer.cdn.mozilla.net/pub/firefox/releases/63.0.1/win32/en-US/Firefox%20Installer.exe

Is the problem at my end or theirs? If the former, what do I need to do to return to the behaviour for FF 62?

Hey Guys and Gals,

I have a website problem with Firefox in Windows 10 Home 64bit oem.

I am trying to get to Cyberlink.com and I get error . I also get error if I try using Chrome. Attached at 2 screenshots, 1 FF and 1 Chrome.

I cant access the site using either browser in wiindows 10.

Microsoft Edge accesses it fine thou. Also I have a Linux virtual OS on my system and I can access Cyberlink.com using firefox in it.

I thought maybe it was my system but it also happened on 2 other computer running Windows 7. But to be on safeside I ran Windows 10 troubleshooter and no problems were found. I ran SFC /scannow from Elevated CMD prompt and it found no errors. I than ran a DISM /Online /Cleanup-Image /CheckHealth and it found no problems.

Anyone else have an issue accessing Cyberlink.com (cyberlink dot com) just in case links are blocked?

And how would I fix the issue if it is only my system?

Please let me know. Thanks in advance Gren

Since up date on 3rd Nov, I have been having problems. I cannot make a google search or open Facebook as I get an insecure certificate notice. However, I am able to open other https sites, such as Hotmail. I have tried adjusting the clock, rebooting.

In addition, all the web pages and passwords saved in options have disappeared. I have relied on this for storing my passwords.

I sent a Facebook post to ask this question. I am trying to sync my two computers Firefox passwords. I created an account, confirmed email. Downloaded and opened up Firefox on new computer. But literally no website can be opened on new Firefox. Including firefox login site. The error I get is

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

Can you help me fix this, so I can use your browser?!

Thanks

I've had trouble accessing websites that use a certificate that's signed with the DigiCert Root CA. As an example, if I open up blog.mozilla.org, I get a SEC_ERROR_UNKNOWN_ISSUER.

This is somehow related to my user profile. If I create a new profile, the problem disappears.

I've tried deleting cert*.db in my profile directory to no avail. I checked about:config and I couldn't find any relevant non-default configuration.

To my surprise, if I want to manually set the trust of the certificate in the certificate manager ("Edit Trust"), it tells me that the certificate is trusted. However, if I click on "View Certificate", I get the following error: "Could not verify this certificate because the issuer is unknown."

I don't know much about CAs, but it seems to be surprising how the issuer of a Root CA could be unknown, isn't that the whole point of a Root CA that it does not need to be signed by another certificate?

The more important question: Where in my profile may I have a non-default option that causes Firefox to not trust the DigiCert Global Root CA?

For years I have used Firefox and been able to login to my NatWest Account - suddenly I am no longer able to have this facility. SECURE CONNECTION FAILED - The connection to the server was reset while the page was loading. The page you are trying to view cannot be shown because the authenticity of the received data couldn't be verified. Please contact the owners of the website to inform them of this problem.

I looked on your help site to see if there were others with this challenge and found some comments from some sanctimonious prat to the effect that this should be remedied by the website owner and that eventually the website would no longer be able to be accessed by any other browser such as Chrome, Edge etc. Great, but I need to see my bank accounts online and rather than change banks, I am changing to Edge so that I can. Eventually NatWest may have to change their security but until then I am going to move away from Firefox, and, I know I only contribute a small amount to your "cause" every year but I shall take that away as well - you are too "holier than thou" in your approach to security and take no thought of how its implications affect the user.
