Since the beginning of the year none of the sites I visit that require a certificate work. If I back date my system to say 12/23/2015 they work fine. I don't seem to have this issue with Internet Explorer. I'm not sure if this is a date issue or and issue with version 43.0.3 which I installed on 1/2/ 2016. Help!

The issue is with my firefox installed on my dell inspiron, working on windows 8.1. I am unable to access any site, even the google home page does not open and displays "Insecure connection" with error code: SEC_ERROR_UNKNOWN_ISSUER. I am writing to you from my computer but the problem is with firefox installed on my dell inspiron. I tried to download some malware scanners mentioned on the mozilla support site but I'm unable to load any site on the laptop.

When I attempt to buy a product online using Paypal I get an Untrusted Connection message. If I open Safe Money and perform the transaction from there, I do not have a problem. This was not a problem with earlier versions of Firefox.

Message text. "This Connection is Untrusted You have asked Firefox to connect securely to www.paypal.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. 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."

I have tried to follow all the support pages presented on this topic, but to no avail. I have uninstalled Firefox and downloaded a fresh copy, but that did not help either. Maybe there must be some file left behind which is affecting the new copy, but I can not find it.

I have never had this problem before. It is effecting sites like Google, etc.

So basically all https sites are untrusted connections

I need a fix or I will be forced to stop using my favourite browser.

Firefox considers Add-ons link and all links untrusted. I can't even connect to disable add-ons. I reinstalled firefox and it was working then it stopped all my connections as untrusted. Guys, you have a problem here. I'm not the only one. Is this a Firefox/Lastpass issue?

Hi,

I have a brand new system running Windows 10. I have restored my Firefox settings from my old system with Mozbackup. Now, whenever I do anything Google related I get this message "This Connection is Untrusted" If I use another search engine, everything works fine, as long as I don't want to go to a Google site!

Mozilla. I have a Windows 7 desk top 64 bit computer. Since installing both as 32 bit and 64 bit Firefox these past two days, It has become impossible to access some sites including my blog on blogger (www.limesstones.blogspot.com) and the Familysearch.org website. I am sharing here just one image.

I did the following that did not change anything:

"KB Solution ID: KB3126 |Document ID: 14085|Last Revised: December 11, 2015":  " http://support.eset.com/kb3126/?viewlocale=en_US ".

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

I do have ESETNOD32 antivirus on my computer. I have no idea what other websites that I can't access as I've been 'stuck' just trying to get these two to open up for 3 days now. I recently changed from a Windows XP computer where I had no problems at all like this using Firefox.

So, if anyone has any idea what else I can do, please let me know. Thank you. Screen prints are below. I added the certificate for Familysearch.org and how it looks like screen with the big white background and is not operational as a website.

Add Exception for Hardware Appliance Not Working on 37.0.1

Before I upgraded to v37.0.1 in the last week I was using v31. I used v31 to connect to a EMC VNX5400. The connection to the appliance is a secure connection and when I browsed to the appliance the very first time (many moons ago) I had to add an exception. No biggy. Upgrading over the years it has never been necessary to add an exception again, because I just upgrade FF.

However, after the upgrade to v37.0.1, I browsed to my appliance like always but was confronted with the "This Connection is Untrusted" dialog. Which wouldn't be a problem except, when I click on the "Add Exception" nothing happens.

I have deleted the existing certificate, which was still there by the way, from the certificate store in Options->Advanced->Security.

Manually trying to add the exception also doesn't work. I attach a screenshot of this.

Any ideas why FF is behaving in this way?

Locking duplicate thread.
Please continue here: [/questions/1091977]

When I search for something on Google using the search bar it says Untrusted Connection, and it doesn't let me "Understand the Risks" and go through. I'm able to get to Google.com but when I search for something it comes up glitched looking (Shows the old Google Logo, etc.) it doesn't let me use the features such as Images, News, Search tools. It automatically goes to Untrusted connection.

Also when I go to Google.com it says Not Secure Connection.

I'm trying to use name.com but getting "secure connection failed", I contacted them regarding the TLS mechanism mentioned in the troubleshoot but they said there's nothing wrong. I still can't access the site or find solution. I've cleared my browser cache and cookies, and checked the site security, which says it's not secure and that I haven't granted any special permissions. So I tried to do that, but there were no permission options, (I found these instructions in the forum: "the address bar and Left click the icon. A window for displaying site information should come up. Select More Information. Now select Permissions. In the menu" <--- not there, see attached pic). Any further instruction would be most welcome and appreciated. Thanks Julie

Firefox just started blocking nearly all websites, including the Firefox website, as untrusted. It won't let me add any websites to the trusted locations. I went to the Mozilla support website through Explorer and tried the fix (delete the cert8.db file and restart Firefox)but it did not work. I tried disabling ESET and restarting Firefox but that didn't work. I refreshed Firefox but that didn't work. All of my favorites work fine from Explorer. Right now Firefox is useless for me.

I installed the httpseverywhere add-on. I don't know if it has anything to do with the problem I am having but every time I try to access a page nearly all pages but not quite all I get a warning instead of what I am looking for. The warning reads This Connection is Untrusted You have asked Firefox to connect securely to... (some URL (the one on my screen now is "add-ons.mozilla.org")), but we can't confirm that your connection is secure.... The goes on with explanation of why this could be as well as what I should do about it. It then gives me a button that reads "Get me out of here" and a link "Technical Details" I have tried everything including resetting Firefox to its original settings, reinstalling Firefox, uninstalling and reinstalling Firefox. The computer is a Dell Latitude, I just upgraded it to Windows 10 and installed Firefox. Do I need to revert to Windows 7.1? How can I get my favorite Web browser back to usability?

I have a website that is secured with TLS. I can access it via IE and Chrome, without trouble. I need it to be accessible with Firefox also... so as to have all browser choices represented. Site: https://368mibn.com/gallery

The main site https://368mibn.com is accessible via firefox, but the /gallery portion uses smart card authentication.

I have included an image of https://www.ssllabs.com/ssltest/analyze.html?d=368mibn.com which gives my site an A+ rating.

I cannot figure out what the problem is.

Any ideas would be appreciated.

When I try to connect my granddaughter's laptop to YouTube, Firefox says, "This Connection is Untrusted." It won't let me continue because it says YouTube uses HTTP Strict Transport Security. I have no problems with any other websites.

The error code is sec_error_unknown_issuer

The laptop uses Windows 10, which I despise, and is an HP Pavilion x2 11-h110nr.

Please help; YouTube is apparently vital to her continued existence.

I did a Refresh on Forefox and it stored an Old Folder on my desktop which I accidentally deleted and removed from the Trash.

Now my Forefox won't open Google, Hotmail and many other web pages saying that it is not a Trusted Sote and is missing certificates.
