And many other URLs, including Mozilla (!), so Firefox 40+ does not work (and I had the same problem on 38.0.1). I am using Yosemite (OS 10.10.5) on a MacBook Pro, but I had this same problem using OS 10.7.5. This is the message I get:

"This Connection is Untrusted

"You have asked Firefox to connect securely to youtu.be, but we can't confirm that your connection is secure.

"Normally, when you try to connect securely, sites will present trusted identification to prove that you are going to the right place. However, this site's identity can't be verified.

"What Should I Do?

"If you usually connect to this site without problems, this error could mean that someone is trying to impersonate the site, and you shouldn't continue.

"This site uses HTTP Strict Transport Security (HSTS) to specify that Firefox only connect to it securely. As a result, it is not possible to add an exception for this certificate."

"Technical Details: "youtu.be 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)"

Sometimes I get a page, such as the mozilla.org page, which has no graphics and is in bare outline form.

Firefox automatically updated itself and installed "Firefox Quantum" 60.0.2 I see - 64 bit - on Windows 10 on a Dell laptop.

Never had this problem before - but when loading Ebay pages, the main body of the advert page fails to load and the full message I get instead is below - I've tried switching the proxy settings to "No proxy" or "Use system settings" and sometimes page loads correctly once but then it fails again! Have cleared cache/cookies, have refreshed, have restarted ...

Very frustrating and this is about to lead me to give up finally on Firefox and move to Chrome.

"Secure Connection Failed

An error occurred during a connection to vi.vipr.ebaydesc.com. SSL received a record that exceeded the maximum permissible length. Error code: SSL_ERROR_RX_RECORD_TOO_LONG

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 uses security technology that is outdated and vulnerable to attack.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?

So when I try to visit archive.org or its wayback machine, I get "Secure Connection Failed" Two widgets are offered: a tickbox for reporting issues and a [Try Again] button. Your Help says to click on the [Advanced] button but there isn't one.

Before anybody gives me a lesson in online security, I would ask that you focus on your usability issue and not my personal habits, thanks.

Yesterday I installed FF 43.0 - 64bit. I did as clean install as I could, uninstalled old version, and deleted from HDD every "mozilla" and "firefox" directory I could find. Since then, I am unable to access next sites (I believe list is not complete): https://www.google.com/ https://www.facebook.com/ https://www.google.com/maps https://www.google.rs/?gws_rd=ssl

Error msg is alwaays the same: "You have asked Firefox to connect securely to www.google.com, but we can't confirm that your connection is secure. Normally, when you try to connect securely, sites will present trusted identification to prove that you are going to the right place. However, this site's identity can't be verified.

Sites that I can normaly access with this FF are: https://support.mozilla.org/en-US/ https://translate.google.com/ https://mail.google.com/

All other browsers can access all sites without problems.

Hello, for the past 2 days my Firefox on my laptop has been acting weird when it has suddenly refreshed itself. When I go to the Add-ons page, the graphics looks very poor (see attached image) and so does Youtube. I went to see if any plugins were having issues and saw that the Java toolkit is at some vulnerable state and cannot be accessed (Firefox simply won't let me to that Java page as it is untrusted). I was trying to re-install the Session manager add on, but the entire graphics of that Add-ons' page looks disabled. My Firefox is up to date, according to the to Firefox itself. Please advise me what to do, as I would very much like to get my old (proper working) Firefox back, and which would be the best way to uninstall it, as clearly that didn't work either?

Thank you all in advance.

Hello,

Just yesterday I started having issues on my computer with Firefox. I play Elite Dangerous and went to the forums to check a recent update, and instead it sends me to an error screen with the message: "SSL_ERROR_RX_UNKNOWN_ALERT."

Screenshots:

I refreshed firefox, deleted cache data/cookiees, etc. I also uninstalled AdBlockerPlus thinking that was the problem. None of these solved the issue, and Firefox works fine on my home internet (same internet as this PC) on my Windows Surface Pro 3 tablet.

Thank You

"The requested URL was rejected. Please consult with your administrator. Your support ID is: 11373612934950299921" (with a different number each time)

I've cleared my histories, cache and cookies. My Firefox updates itself.

Going to other sites is fine.

I've spoken to the company, they don't know what's happened and are not having this problem themselves or with any other customers.

Which administrator might it be referring to? Can anyone help? (I'm not sure whether to click on 'Share Data' below; let me know if this would be helpful.) Many thanks.

I just installed FF 63 on a 64-bit Windows 7 machine, and I'm getting SEC_ERROR_UNKNOWN_ISSUER errors at many, but not all, websites. Reaching the same websites via the same URLs using Chrome works fine.

All discussions of this problem seem to lead to https://support.mozilla.org/en-US/kb/error-codes-secure-websites?redirectlocale=en-US&redirectslug=troubleshoot-SEC_ERROR_UNKNOWN_ISSUER, but it's not helpful. My antivirus is Bitdefender Free, which appears to have no option for disabling the interception of secure connections.

Running FF in safe mode behaves the same as in "normal" mode: I get SEC_ERROR_UNKNOWN_ISSUER errors at many (but not all) websites.

Help? As things stand now, FF is pretty close to useless for me.

Hello

I'm having troulbes accessing HP iLO with FF 36.0 on Ubuntu 14.04 LTS, getting the following error message:

========================

Secure Connection Failed

An error occurred during a connection to 172.25.X.X. Issuer certificate is invalid. (Error code: sec_error_ca_cert_invalid)

   Please contact the website owners to inform them of this problem.
========================

It seems to work with other browser such as Chromium, so the problem seems to be FF 36.0. Unfortunately, I don't have an "Add exception" button in FF that would allow me to bypass this warning.

I've already followed the following links: https://support.mozilla.org/en-US/kb/secure-connection-failed-error-message https://support.mozilla.org/en-US/kb/troubleshoot-extensions-themes-to-fix-problems

But I didn't managed to get it work. Any idea how to get it fixed?

I'm still getting the "Secure Connection Failed" error on various sites.

Only in Firefox. Internet Explorer and Chrome both load the sites correctly.

Tried to connect to https://www.ghacks.net/2016/12/19/remove-g-button-android-keyboard/

  An error occurred during a connection to www.pcmag.com. Peer received a valid certificate, but access was denied. Error code: SSL_ERROR_ACCESS_DENIED_ALERT

  Please contact the website owners to inform them of this problem.

Restarting in safe mode does not fix the problem.

Changing security.tls.version.max and security.tls.version.min to 0 and restarting does not solve the problem.

Trying with a new profile with no extensions or other changes from the default had no effect.

Firefox 56.0b7 (64-bit) for Windows.
