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.

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.

FireFox is blocking many sites and says This Connection is Untrusted

many sites is blocked by firefox like facebook , yahoo mail and even this site.
its saying This Connection is Untrusted
and this sites working on other browsers
and i'm sure that the pc date is right and up to date
so what???

I have been having the same problem, chased my tail around for ages and then realised that my system clock was out of date because my laptop battery is toast.
I reset my clock to today's date and the certificate errors disappeared.
Check your clock?

Why can't I connect to web sites that require my user name and password. window pops up saying this connection is untrusted.

This Connection is Untrusted
You have asked Firefox to connect
securely to cards.chase.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.
Technical Details
cards.chase.com uses an invalid security certificate.
The certificate will not be valid until 5/4/2010 5:00 PM.
(Error code: sec_error_expired_certificate)
I Understand the Risks

Can you post links to pages that give that error?
Did you try to remove cert8.db in the [[Profiles|Profile folder]] or tested with a new profile ?

My FireFox Keeps Saying This Connection Is Untrusted

It Happened After I Reset FireFox.

hello, first please make sure that the date & time is 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]]

Why does Firefox say "This Connection is Untrusted" for most websites?

Firefox tells me the connection isn't trusted for pretty much every site I attempt to go to. I can't bypass it and I have tried everything I read in the support articles, changed settings, resetting and restarting etc. Nothing works. Please help!

Check the date and time 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.

I keep getting a message that says "this connection is untrusted" whenever I try to access ANY website

I looked through the previous questions and deleted any suspicious software (there really wasn't any, just a bing toolbar). I deleted firefox and reloaded it. I bought Norton Antivirus and ran a scan - nothing. Date and time on my computer are correct. Explorer works fine. Help! I prefer firefox but I can't access ANY website. I get this message every time.

I already went through all the instructions on the Firefox support forum and nothing worked. The issue can't be the website certificate because it happens for EVERY SINGLE WEBSITE I attempt to access. Regardless, I did add an exception for Facebook per the instructions. That caused a strange, unformatted page to come up. I have since read that to do an exception is dangerous as it can cause MORE unwanted malware to infect the computer.
I did, however, figure it out on my own so maybe this will help people who are experiencing this problem in the future: After reading the past posts from people who experienced the same thing, I realized that in every case, the solution was to remove some sort of unwanted software (malware). I am very careful to NOT download software and I noticed that another victim of this said the same thing so this one is sneaky. I even bought new antivirus software (Norton), ran a scan and the problem was not found.
I went to Programs "uninstall programs," sorted them by date and removed anything that looked suspicious that was recent. I had something with the word, "rocket" in it. It looked like a game. There was also one other program that I removed (can't remember the name of it now). Removing those didn't solve the problem, so I went back through all the programs on my list and removed anything that said "toolbar" on it, even if it sounded trusted (I had a bing and a google toolbar). That didn't seem to work either so I sorted the programs by date again and I noticed that the "rocket" software was STILL THERE.
I right clicked on it and then clicked on "uninstall" again. It takes an exceptionally LONG time for that program to uninstall AND nothing shows up on the screen. The computer just sort of sits there and does nothing. I walked away and when I came back (about an hour later) the program was gone from the list.
Firefox works now. I'm not getting that message anymore, but here's the deal: I am not 100% sure which program was the problem. It was either that rocket software or one of the toolbars. Regardless, the answer always seems to be some sort of unwanted malware so I would recommend that any victim of this problem try uninstalling suspicious programs as a FIRST step. And that means ANY suspicious programs that are RECENT, regardless of whether they look like games or antivirus or whatever. If it's recent and you don't remember downloading it, uninstall it.

I keep getting This Connection is Untrusted and I'm on a secure server. What is this and how can I fix it?

I have checked the security information and nothing seems to affect this issue. I've restarted my computer with no resolution.

hi vijaysampath, 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:

please report back with those two pieces of information. thank you!

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.

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.
I have tried following Solution:
1. Uninstalling firefox completly including deleting profile + reboot + install
2. Reset the Firefox
3. Clear the caches and evreything.
But could not solve my problem so now I am posting this questions. I am using Latest Firefox with Windows 7.
Please help me to get rid of these issues as I am highly dependent on Firefox.

Getting this message "This Connection is Untrusted" and I need this next page to come up so that I can put in a job submital. Need to allow this to open????

I am putting in for jobs and it is not letting me go to the next page. I am getting the below message and cannot figure out how to make this problem stop. I did not have this problem in Explorer. I am getting this message...I have say allow it, but then I get this message and cannot go any further - The certificate is not trusted because no issuer chain was provided
This Connection is Untrusted
You have asked Firefox to connect securely to psappprd1.is.wfubmc.edu:8002, 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.
psappprd1.is.wfubmc.edu:8002 uses an invalid security certificate.
The certificate is not trusted because no issuer chain was provided.
(Error code: sec_error_unknown_issuer)

this problem when i change my motherbord , Happened.
i solved this , by set the time & date in windows & '''mainbord time in bois''' .
it's fixed.

Can't skip "This Connection is Untrusted" error page

The SSL certificate for one of the sites I use expired today a couple hours ago, and the devs of that site still haven't had spare time to update it yet. Suppose it's not a big issue, in most (other) browsers you can just review the problem and click on "continue anyway" link or something like that, when you're sure that the certificate was expected to become invalid. So you can visit the page requested with broken certificate in _single_ click. But not in Firefox.
As I remember - some time ago on the Cert Error page there was "I understand the risks" paragraph with the button "Add exception" below. Looks like it got disabled in Firefox 30 as I don't see it there. Okay, I googled around and found out that in about:config page there's a secret option browser.xul.error_pages.expert_bad_cert which was in disabled state by some reason (I personally haven't ever touched it before). Okay, now I'm able to open the ugly "Add exception" window, but when I add exception - nothing happens. Neither temporary not permanent exception option allowes me to view the site. "This Connection is Untrusted", browser says. Period.
After that I've tried to install "Skip cert error" add-on - with no success. Even if I add the site URL to whitelist in add-on options, which "in theory" should bypass ANY security checks for this exactly domain - then I still end up staring at "This Connection is Untrusted" error which simply can't be bypassed by any means.
The sites I've tried to reach are https://lists.openwrt.org and https://forum.openwrt.org. It's interesting though, the certificate is also expired at https://openwrt.org, but that site can be added to exception list and then firefox opens it. However I see completely NO WAY to make firefox open https://lists.openwrt.org or https://forum.openwrt.org.
I've run out of ideas and came here. Hope somebody knows how to workaround this issue.
PS: I wonder why the hell there's no option to bypass the check by some _simple_ means like in other browsers so that I could reach requested site in seconds rather then searching for settings/addons/workarounds for hours. Thank you firefox for such enourmous care for security, you've made me run Internet Explorer again...
Update 1:
It appears that in this case the certificate was registered for domain openwrt.org, but was also used for forum and lists subdomains. Now it is expired, but the expiration issue can be ignored by exception list only for openwrt.org itself. Other subdomains are actually added to exception list, but it doesn't work for them, so that browser is stuck at "untrusted connection" error which can't be ignored or skipped. What a shame.
Update 2:
I was quiet wrong in Update 1: in fact the SSL certificate for openwrt.org was Level 2 certificate with correcly registered subdomains like forum.openwrt.org and lists.openwrt.org. However when the certificate expired, only openwrt.org exception worked and the site was browseable. All the subdomains could be added to exceptions but regardless of that fact firefox refused to open those sites and was stuck on unskippable "untrusted connection" error page.
For now openwrt.org maintainers have already renewed their certificate so the problem can't be observed on those domains anymore. However I believe that the problem in firefox exceptions handling still exists and should be fixed in future firefox releases.

Hi kozaki, this thread is about an older version of Firefox. Could you start a new question?
For what it's worth, I see the "I understand the risk" section of this page in Firefox 33.0.3: https://forum.anomos.info/ -- but I have not added an exception for the top level site, so maybe that's a partial explanation for the difference.
Also, a new release of Firefox is out today which makes some changes for certificate issues.

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:
* [http://www.microsoft.com/security/scanner/default.aspx Microsoft Safety Scanner]
* [http://www.malwarebytes.org/products/malwarebytes_free/ MalwareBytes' Anti-Malware]
* [http://support.kaspersky.com/faq/?qid=208283363 TDSSKiller - AntiRootkit Utility]
* [http://www.surfright.nl/en/hitmanpro/ Hitman Pro]
* [http://www.eset.com/us/online-scanner/ ESET Online Scanner]
[http://windows.microsoft.com/MSE Microsoft Security Essentials] is a good permanent antivirus for Windows 7/Vista/XP if you don't already have one.

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

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