I noticed that I get a "This Connection is Untrusted" error in Firefox. I use KIS 2015. I reseted Firefox. Pls advise

I've just installed the latest version of KIS and now I"ve noticed that I get a "This Connection is Untrusted" error in Firefox whenever I try to go to either of those websites. I reseted Firefox. I am unable to open anything through firefox-- my yahoo mail, google accounts, search through google, etc. Any suggestions on how to get firefox to work?

I am trying to access an https site and am getting a "This connection is untrusted" message. I am willing to bypass, but when I click the Add Exception button and then try to click the Confirm Security Exception button, nothing happens.

unfortunately the do_not_trust 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.

afterwards, run a full scan of your system with different security tools like the [http://www.malwarebytes.org/products/malwarebytes_free free version of malwarebytes] & [http://www.bleepingcomputer.com/download/adwcleaner/ adwcleaner].

This Connection is Untrusted Error

Having trouble with my Mac or Mozilla. I keep getting the "This Connection is Untrusted" on 3/4 of the websites I visit during a session on the internet. I have made sure that I have the Use SSL 3.0 and Use TLS 1.0 Protocols checked.
I might have deleted some security certificates or added some add-ons right before I noticed the error message.
Anyone have any ideas?
Thanks.

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.

Is that content loaded in an iframe?
You can check that via the right-click context menu to see if there is a "This Frame" item. 
If that is the case then try top open the frame in a new tab or otherwise check the Technical Details of the error message.

Cannot access any https sites, clock is OK, get This Connection is Untrusted error message.

All works OK on Chrome and IE, but Firefox just suddenly stopped access to https sites yesterday, e.g. Google, Facebook and Linkedin. Non secure http sites are OK though. "This Connection is Untrusted" is the error message and technical details are www.google.com.tw uses an invalid security certificate. The certificate is not trusted because no issuer chain was provided. (Error code: sec_error_unknown_issuer). I've tried all the Mozilla support suggestions, clock (which was always correct), reset Firefox, etc. No change so far, I hope you can help fix this issue.

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.

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.

This connection is untrusted error reportwhen trying to check e-mail

Every time I try to get my Yahoo or Google e-mail, I get the following message "You have asked Firefox to connect securely to us-mg5.mail.yahoo.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 uninstalling and reinstalling Firefox, and tried deleting cert8.db. file and nothing has worked.
How do I fix firefox so that it will work with two of the most popular e-mail addresses?

hello bgreenberg, maybe your antivirus software is interfering here. does it make a difference when you disable the scanning of encrypted connections/https within the kaspersky network settings?

"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:

"This connection is untrusted" shows up CONSTNATLY!!! and I cannot move the page down to get to the bottem of I understand the risks to override it. How do I do that or how do I TURN IT OFF!!!

Even sending this message gets the" This connection is untrusted"!!!!!How is that for stupid!!! How do I turn it off or do I have to use some other site and wipe firefox off my computer.

Just got this warning for facebook, Amazon, and Google, I have just told my clients to stop using firefox until the problem is fixed, it is a support nightmare because you have inexperienced users calling in convinced that they have a virus on their computer, and that they need to unplug the internet to prevent anything bad from happening.
I had one customer call in and say, "it says get me out of here, Oh my God what have I done I should never have gone online"
You know what can we have a better more accurate statement, on that warning, like Hi, thanks for stopping by this website may be sharing a security certificate with a parent organization, it may not really be a bad thing we just wanted you to know about it before you go on your merry way. Oh and by the way were going to make you jump through hoops and clicks check boxes and do this and do that before we let you go on your merry way, wait, " Are you really sure that you want to be doing this?" Do you know what your doing, perhaps you should call your ISP for advice, and get support from someone who has nothing to do with this issue.
Thanks Guys, appreciate all the calls, perhaps I should give them your email address. $%^$%#$

Mac users get "this connection is untrusted" message although I have an SSL cert

I have a new ecommerce website for which I paid to have an SSL certificate. Mac users browsing in Firefox are getting a "This connection is untrusted" message. Users are offered a "Get me out of here button" or can click on "Technical Details" or "I understand the risks". Most choose to get out.
Mac users can browse in Safari with no problem, PC users don't have the issue in any browser, including Firefox.

You can check the certificate chain via a website like this:

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.
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.

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!
