This Connection is Untrusted - every website

I keep getting the 'This Connection is Untrusted' message. It's on all websites.
== This happened ==
Every time Firefox opened

Hey, I had this same problem. The problem is caused by your computer time and date being off from the actual time and date. There is a very simple solution. Check your date and time on your computer. If it is incorrect change it back to the right time. Make sure the month and year are correct too. That should fix it.

This Connection is Untrusted - Vodafone website, issue only occuring with Firefox

Finding Firefox is giving issues with any https://online.vodafone.co.uk/ url
Other browsers aren't giving the same issue and Vodafone themselves weren't very helpful as they seem to think the browser is at fault.
Any suggestions (that reasonably don't comprimise my security) would be appreciated

They previously didn't send the required intermediate certificates and have corrected this on their server, so they are send now and Firefox no longer has a problem.

Ugent help - Every time i go to a secure website firefox latest version says This Connection is Untrusted. This was never there before and now its appearing

Every time i go to a secure website using firefox latest version i get an error saying "This Connection is Untrusted" This was never there before and now its appearing. My computer clock and date is correct and i have tested out all plugins that they are updated. Also did a scan on all viruses and spyware nothing there any help please.

Sorry, I didn't look at all the images.
You can see that the certificate is issued by your security software (Firewall): ESET SSL Filter CA 
So you will have to disable that filter or install the ESET root certificate that chains to that certificate.

Every website that I try to access, I get this mesage ''This Connection Is Untrusted". Please advise.

Every website that I try to access, I get this mesage ''This Connection Is Untrusted". I tried to add exceptions, but that didn't work.

Hello,
This is generally not a good thing if you are seeing this message for all websites. Can you please check if you are seeing this issue if you open the browser in Safe Mode (instructions below).
Also, request you to scan your computer for any malware to ensure that there is no issue with some malicious software running on it.
<hr>
'''Safe Mode'''
'''Try Firefox Safe Mode''' to see if the problem goes away. Safe Mode is a troubleshooting mode, which disables most add-ons.
''(If you're not using it, switch to the Default theme.)''
* On Windows you can open Firefox 4.0+ in Safe Mode by holding the '''Shift''' key when you open the Firefox desktop or Start menu shortcut.
* Or open the Help menu and click on the '''Restart with Add-ons Disabled...''' menu item while Firefox is running.
[[Image:FirefoxSafeMode|width=520]]
''Once you get the pop-up, just select "'Start in Safe Mode"''
[[Image:Safe Mode Fx 15 - Win]]
'''''If the issue is not present in Firefox Safe Mode''''', your problem is probably caused by an extension, and you need to figure out which one. Please follow the [[Troubleshooting extensions and themes]] article for that.
''To exit the Firefox Safe Mode, just close Firefox and wait a few seconds before opening Firefox for normal use again.''
<hr>
'''Malware scan'''
Sometimes a problem with Firefox may be a result of malware installed on your computer, that you may not be aware of.
You can try these free programs to scan for malware, which work with your existing antivirus software:

I get "This Connection is Untrusted" on every website?

I've uninstall firefox and changed the time and I can't get the bowser to work. Every single webpage gets the This Connection is Untrusted message. Every website gets the error message (Error code: sec_error_unknown_issuer). I don't have any problems with IE only firefox won't work. I just bought the computer 2 days ago so im sure its not a virus. I have Kaspersky internet security

It didn't work. I could not find KasperskyAnti-VirusPersonalRootCertificate in firefox. I have windows 8.1 so I don't have a start button. I made hidden folders viewable from the control panel, but I couldn't find the certificate

Every time I try to log into ANY website that is secured, I get an error message "This connection is untrusted."

The error message is:
This Connection is Untrusted
You have asked Firefox to connect securely to www.facebook.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.
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.
www.facebook.com uses an invalid security certificate. The certificate is not trusted because no issuer chain was provided. (Error code: sec_error_unknown_issuer)
If you understand what's going on, you can tell Firefox to start trusting this site's identification. Even if you trust the site, this error could mean that someone is tampering with your connection.
Don't add an exception unless you know there's a good reason why this site doesn't use trusted identification.
Steps I have take so far:
Verified that system clock is correct
Cleared all cache, history, cookies, etc.; didn't help
Started Firefox in Safe Mode; didn't help
Disabled all Firefox extensions; didn't help
uninstalled and reinstalled Firefox using Control Panel; didn't help
Ran Microsoft Safety Scan for malware; nothing was found
Other information:
This problem exists ONLY in my user profile and ONLY in Firefox. All 5 other users can run Firefox with no problem. I can run IE and Chrome with no problem.
Problem exists in ALL secured (https) sites.
I use Avast and Windows Firewall. Had never heard of ESET or BitDefender before searching these forums.
A lot of the sites don't give me the option to Make an Exception. The two that I tried to make exceptions for, still wouldn't open.
Run Windows 7 64-bit

unfortunately the fiddler2 issuer in certificates might be a sign of unwanted software present on your pc that is intercepting secure network traffic. please go into the system control panel and uninstall programs like BrowserSafeguard, BrowserSafe, SafeGuard or other software that sounds suspicious and didn't get installed by you intentionally.

How to permanently remove "This Connection is Untrusted" notification for all future websites everywhere forever?

Dear Mod/Helper/Whoever
Please read this entire post before answering since it addresses virtually all the most popular "solutions" for this problem and they DON'T WORK.
I've already found this and it was of no use: https://support.mozilla.org/en-US/questions/1015256?esab=a&as=aaq
The moderator's blatant copy-paste response was an insult and not helpful at all.
My system date is ok and the cause of invalid certificate is the LEAST of my concerns. I just want to browse the website and not get ANY warnings about ANY invalid certificates or ANY risks involved, period. All popular workarounds with settings/advanced/validity properties have been tried but none of them fix this for me. I want FF to accept all invalid certificates instantly without notification or warning, no matter what.
I want to remove the warning screen "This Connection is Untrusted" permanently for all future references, so that I don't even see any errors related to it when I browse a website.
I'm not here to argue the merits or lack thereof for this action, I just want to get rid of it.
I'm running a lot of custom software on my comp and I have 3 LAN cards connecting me to 3 different networks with varying degrees of security and this notification is a huge pain in the... back, because it eats my time every day.
I've been using Firefox for years exactly because it didn't have stuff like this in the past - I could visit all the funny/suspicious/malicious websites without problems, where IE would have died 10 times over. Sadly that FF feature began changing to the worse in the past years, an ever-increasing slope downwards for this once great web browser.
I KNOW all the risks involved and I don't care. In fact I encourage websites to try and install "stuff" on my computer because as I mentioned, this is a special computer. I'm visiting 40-50 websites with that prompt DAILY because that's what I do for a living. Every time I have to add an exception is a wasted effort and time. I'm running other browsers as well but FF is my focus due to its popularity.
Please for the love of all that is sacred, provide some sort of workaround for this without the need to install an addon or click "I understand the risks" a gazillion times. An "about:config" variable would be nice but apparently it's not there, I looked.

That is not possible as that would expose you and other Firefox users to unacceptable security vulnerabilities.
The normal procedure is to contact the website maintainer and ask them to fix the certificate chain or install missing root certificates in Firefox and set the trust bits accordingly.
If you do not care about certificates then why don't you install proxy software and use that proxy and let it handle the certificates and import the root certificate of that proxy in Firefox?

I just downloaded the new version of Firefox and now every site I used to use such as Facebook, Twitter, and Youtube show "This Connection Is Untrusted"

I just downloaded the new version of Firefox and now every site I used to use such as Facebook, Twitter, and Youtube show "This Connection Is Untrusted". Even when I do accept the risks the site no longer looks the way it's looked for years. Twitter doesn't even give me the option to accept the risks at all and shows this error (Error code: sec_error_unknown_issuer). I've tried resetting Firefox, I've checked the time and date, and I've removed and added Firefox to see if that would work. Nothing seems to be working so I can see the sites the way they normally would be instead of "coded". Can anybody help me please?!!! Thanks

ok, unfortunately the fiddler2.com issuer in certificates might be a sign of unwanted software present on your pc that is intercepting secure network traffic. please go into the system control panel and uninstall programs like BrowserSafeguard, BrowserSafe, SafeGuard or other software that sounds suspicious and didn't get installed by you intentionally.

hello, first please make sure that the date, time & timezone are set correctly on your system. if this doesn't solve the issue (or it is already set properly), a possible solution depends on different factors:
* what is the '''error code''' shown under ''technical details'' on the error page?
in case the error code equals ''sec_error_unknown_issuer'', please attempt to add an exception on the bottom of the error page & inspect the certificate (see the screenshot attached for instructions):
* which '''issuer information''' does the certificate contain?
thank you!
[["This Connection is Untrusted" error message appears - What to do]]

I got "This connection is untrusted," on a website I visit everyday. I wasn't given any options to choose for a solution.

I tried to log into a site that I use on a daily basis for my freelance writing. In the middle of the page - where it lists my reports - is a box that says, "This connection is untrusted." I read some other Help articles and one said there should be three options, one which allows me to continue. In my instance, there were no options to do anything to continue or to leave the page.

I don't know what an iframe is. When I right-clicked, it said that this website does not supply ownership information.

Website box says, ' this connection is untrusted, can't confirm it's secure'.

I'm trying to open a secure website. a box comes up, it reads:
'this connection is untrusted... can't confirm connection is secure... this sites identity can't be verified... this error could mean someone is trying to impersonate the site.' I called the company and they said it is my browser. I don't know what to do?

Check the date and time and time zone in the clock on your computer: (double) click the clock icon on the Windows Taskbar.
Check out why the site is untrusted and click "Technical Details" to expand this section.
If the certificate is not trusted because no issuer chain was provided (sec_error_unknown_issuer) then see if you can install this intermediate certificate from another source.
You can retrieve the certificate and check details like who issued certificates and expiration dates of certificates.
*Click the link at the bottom of the error page: "I Understand the Risks"
Let Firefox retrieve the certificate: "Add Exception" -> "Get Certificate".
*Click the "View..." button and inspect the certificate and check who is the issuer of the certificate.
You can see more Details like intermediate certificates that are used in the Details pane.
If "I Understand the Risks" is missing then this page may be opened in an (i)frame and in that case try the right-click context menu and use "This Frame: Open Frame in New Tab".
*Note that some firewalls monitor (secure) connections and that programs like Sendori or FiddlerRoot can intercept connections and send their own certificate instead of the website's certificate.
*Note that it is not recommended to add a permanent exception in cases like this, so only use it to inspect the certificate.

Firefox Nightly keeps bugging me with "This Connection is Untrusted" on every single site I visit

So I am trying out the new FireFox Nightly, as it was suggested by a friend to me. Now I am liking it at first, but when I remove all my old FireFox stuff (completely uninstalled as there was alot of useless junk/plugins/data that I wanted gone) I am now getting this "This Connection is Untrusted" message on every single site I visit! It even says that the mozilla site is dangerous. So is there any way to disable these warnings?

Hello Rykuu, also, check the time and date of your system, if the date and time on the computer are wrong then security certificates may not be valid.
which security software do you have (firewall or/and anti-virus)?
thank you

"This connection is untrusted" for any website I try to visit

Trying to access any website and I get the "this connection is untrusted" error come up.
Sites like the FireFox addons, Facebook, Tumblr, etc etc.
I've tried adjusting my date and time (although it already is on the correct date and time..) and still, nothing.

Example:

I am getting "this connection is untrusted" error messages from Firefox for Desktop when I try to log into certain websites, such as Facebook. Why?

I get this error message "this connection is untrusted" after I re-installed Windows Vista and all my programs. This happened before but after reformatting my computer everything was good. Why am I getting this? Could it be a virus of some sort? It happens when I use Windows Internet Explorer as well....

Hi,
Please check the time/date on the PC. The ideal setting would be to '''Automatically synchronize ...''' in Date and Time > Internet Time.

Firefox (latest versions) on both Mac 10.6 and Windows 7 show "this Connection is Untrusted" on my bank site

This started for me 1/17/2011 on the savingsbank.com website:
Firefox (latest versions) on both Mac 10.6 and Windows 7 show "this Connection is Untrusted" on my bank site https://www.savingsbank.com
NO other browsers - Explorer, Chrome, Safari - give this error box on this site. Please advise if this has to do with the bank site? or Firefox compatibility.
Saw in a forum someone else having this problem and they were told it had to do with their Date and time being off?? I've been on several computers, all with the correct date and time and they've all shown this Insecure Certificate statement on my bank site with Firefox and no other browser.

I've looked at the banking site with IE8 and it does NOT show me that "This connection is Untrusted" window. (please see attached screen shot of viewing the site with IE8) It opens fine and has "Identified by Network Solutions" showing on the address bar as it always does.
The latest version of Opera (not earlier ones) does show a problem with the website's security certificate.
We've contacted the bank about this, and they say there's no problem with their certificate but are looking into it.
My question remains, why only Firefox and one version of Opera claim this and NO other browser?

This Connection is Untrusted - every website
