All personal certificates for loggin on sites doesn't shown - empty storage. Sites saying "You have no certs installed". When I import cert from backup and enter right password I see window "Alert! ... imported successful", but no cert appears at "View certs" - Personal. When I do enter wrong pass importing cert I have an error (so ok).

Linux 3.13.0-44-generic #73-Ubuntu SMP Tue Dec 16 00:23:46 UTC 2014 i686 i686 i686 GNU/Linux Any ideas? Thanks!

On my desktop version of Firefox, the option shown in this screenshot is disabled: http://screencast.com/t/k7YIzNTC9C7. It's not greyed out on my laptop version.

Also, I'm not able to select the "Always Enable" option to always enable notifications from certain websites in my browser on my desktop, but I'm able to do it on my laptop.

Both versions are updated to 36.0.4.

This started July 4th. Unable to access my bank account login page, with either the bookmarked page I have used for years or entering IP address for direct log in to site . I have refreshed. Same problem I called the bank, they had me try Explorer, and it logged in without a problem, so did Chrome. No problem with other browsers. I get a Security Connection Failed page instead of the bank log in page. I have on occasion been able to goggle the bank and log on with Firefox, but not usually. This is the page that pops up instead of the bank log in page. Secure Connection Failed The connection to www.bankofthewest.com was interrupted while the page was loading. The page you are trying to view cannot be shown because the authenticity of the received data could not be verified.

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

When I log into Yahoo mail on Firefox 40.0.3 (on Windows 7) on my company-supplied laptop, I get this message: "You have asked Firefox to connect securely to us-mg5.mail.yahoo.com, but we can't confirm that your connection is secure."

I cannot create an exception: "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."

The "technical details" section states: "us-mg5.mail.yahoo.com 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)"

This does not happen at home, so the company laptop has something to do with it, but, even on the company laptop I do not have this problem when using Chrome, so it's not that the company does not allow access to outside mail.

On Firefox, the problem is intermittent. Sometimes, there is no problem and everything works fine. Clearing history/cookies/cache and restarting does not fix the problem. It sometimes goes away on its own for a little while, but then returns.

I have searched every database I could for answers, but have found no solution yet. The computer clock is correct, I'm not using Avast, etc. (some of the other situations I've run across).

I hope that I can get this resolved, because I'd rather keep using FF, which I've used for years, than switch to Chrome.

Thanks for your help, in advance.

I'm using firefox for windows 7. My firefox now has version 41.0.1. This problem, however, was happened in older versions too.

When I visit https://www.google.com/, then drop down the menu [Tools]-->[Page Info]-->click the [Security] icon-->click the [View Certificate] button. In the Cerftificate Viewer dialog, click the [Details] tab and it will show the Certificate Hierarchy tree. The tree shows like below:

 GeoTrust Global CA <- Google Internet Authority G2 <- google.com

But when I use "openssl.exe s_client" command to test www.google.com:https, it shows below hierarchy:

 Equifax Secure Certificate Authority <- GeoTrust Global CA <- Google Internet Authority G2 <- www.google.com

Does it mean that the certificate "GeoTrust Global CA" is still a intermediate certificate which is issued by Equifax but firefox think it is a root CA ?

I checked the public key of the certificates "GeoTrust Global CA" retrieved from both firefox and openssl, and they are the same as below:

MIIBIjANBgkqhkiG9w0BAQEFAAOCAQ8AMIIBCgKCAQEA2swYYzD99BcjGlZ+W988 bDjkcbd4kdS8odhM+KhDtgPpTSEHCIjaWC9mOSm9BXiLnTjoBbdqfnGk5sRgprDv gOSJKA+eJdbtg/OtppHHmMlCGDUUna2YRpIuT8rxh0PBFpVXLVDviS2Aelet8u5f a9IAjbkU+BQVNdnARqN7csiRv8lVK83Qlz6cJmTM386DGXHKTubU1XupGc1V3sjs 0l44U+VcT4wt/lAjNvxm5suOpDkZALeVAjmRCw7+OC7RHQWa9k0+bw8HHa8sHo9g OeL6NlMTOdReJivbPagUvTLrGAMoUgRx5aszPeE4uwc2hGKceeoWMPRfwCvocWvk +QIDAQAB

Maybe this is a bug that firefox will miss the intermediate certificate when it encounter the circumstances like above.

One particular web site won't load, and I was previously able to view the site roughly 2 weeks ago. It's a free WordPress site/blog.

I keep getting the error message "The connection to the server was reset while the page was loading." I've tried deleting all cookies and emptying the cache with no success. I also tried a "DNS Flusher" with the same result.

I've followed all the recommendations on the Firefox Help link and checked the Community and FAQ sections with no luck.

I can view the page in Safari. The web site owner can view the web site using a setup similar to mine (Mac OS 10.5, Firefox 12.0).

Nothing I know have has changed since I was able to view the site 2 weeks ago i.e., I'm not going through a proxy server nor do I have any secondary security or anti-virus programs running.

Any help would be appreciated.

In my work computer, Firefox always gives "sec_error_unknown_issuer" error and only on HTTPS sites.

I have browsed the forums and understood that this is most probably caused by a sofware that performs HTTPS scanning. (See [this](https://support.mozilla.org/en-US/questions/1030927) and [this](https://support.mozilla.org/en-US/questions/1026631#answer-650916) answer)

However, I really don't know which software is performing the HTTPS scanning exactly.

Is there a way that I can determine which software is doing the HTTPS scanning so that I will be able to add its certificate to Firefox and hence be able to use the Firefox properly?

Thank you very much in advance

Regards

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 don’t know whether this is a problem with Microsoft office, firefox or my machine, I have already contacted apple support, and they said that it was not my machine. When I contacted Microsoft support, after describing the problem they ended the chat without saying anything. So this is what happened: I was at school. I tried to access my outlook email in firefox. I got an untrusted connection page. On the school wifi, since it restricts certain websites, you have to have a certificate installed in order to access secure (ones with lock icon) websites, I think so that the restrictor thing can see what webpage you are accessing. If it can’t read what you are accessing, it doesn’t let you access the page and you either get an access denied page, or on firefox a “this connection is untrusted” page. Earlier in the year I installed the certificate. for Firefox, I could click on a link that they gave us and it installed itself. for Chrome, I downloaded the certificate and imported it into my keychain. So when I got the connection untrusted page on firefox when trying to access a site that isn’t blocked, my school email, which is outlook/office365, since I had heard rumors about an updated version of the certificate, and having to install the new one, I decided to try reinstalling the certificate in firefox. So I used the wifi hotspot on my phone to go to my school email, the page that I couldn’t access before, I went to the school Sharepoint site for tech stuff, and clicked on the link to download the certificate. It said it was already installed. But it didn’t look like it was working on the school wifi, because I still couldn’t use the wifi to access outlook. So I tried to uninstall the certificate. since it said it was a certificate authority, I went into firefox advanced settings > certificates > certificate authorities and deleted the certificate called Bloxx. I might have forgotten a test here that I tried, but not anything else that I deleted. I found that it still wasn’t working. now I couldn’t access outlook at all. I tried uninstalling and reinstalling firefox. But the certificate I had deleted wasn’t there. I looked in my keychain, and I saw that there was no certificate called Bloxx in my system roots, but the other certificates I had seen in the firefox settings were there. When I got home, using time machine I backed up my computer so that anything I did from there on could be recovered. I hadn’t had any system backups before that. I saw on apple forums that I should try to reinstall the OS. I reinstalled OS X El Capitan. I can see the certificate I deleted is now there in firefox, but I am on the wifi at home which is not restricted at all, and I cannot access the office365, outlook, or any websites relating to that, even the products.office.com site. It says the connection is untrusted. However, on chrome, everything works.

I have tried every way possible to fix this error none of the website work the only one that does is yahoo and they all say the same error

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.

www.google.com 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)

i have a website http://gefest.rads-doi.org/index.php/login and cant enter in, got an error "Этот сайт использует сертификат SHA-1; рекомендуется использовать сертификаты с алгоритмами подписи, использующими более сильные хеш-функции, чем SHA-1.[Подробнее] mc.yandex.ru", and all other script stops work. But in firefox on linux it works correctly, what is the problem. And also oncontextmenu doent works as it has to. On many browsers it works normally, and on firefox it doesn,t how can i fix it?

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. 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: www.google.com 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)"

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.

There seems to be an issue with your security certificate.

Latest update to firefox on Windows 10 gives an Untrusted Connection message and the following information which appears unusual:

www.mozilla.org uses an invalid security certificate. The certificate is only valid for the following names: gp1.wac.edgecastcdn.net, wac.edgecastcdn.net, ne.wac.edgecastcdn.net, swf.mixpo.com, cdn.traceregister.com, s.tmocache.com, s.my.tmocache.com, e1.boxcdn.net, e2.boxcdn.net, e3.boxcdn.net, static.woopra.com, assets-secure.razoo.com, ec.pond5.com, images.esellerpro.com, use.typekit.com, static.iseatz.com, static.www.turnto.com, inpath-static.iseatz.com, secure.avelleassets.com, static.dubli.com, cdn1.fishpond.co.nz, cdn1.fishpond.com.au, cdn.optimizely.com, cdn.whois.com.au, ne1.wac.edgecastcdn.net, gs1.wac.edgecastcdn.net, edgecast.onegrp.com, cdn.psw.net, cdn.gaggle.net, fast.fonts.com, ec.xnglobalres.com, images.vrbo.com, cdcssl.ibsrv.net, player.vzaar.com, framegrabs.vzaar.com, thumbs.vzaar.com, content.aqcdn.com, content.ebgames.com.au, content.ebgames.co.nz, images.allsaints.com, cdn1-ssl.iha.com, cdn2-b.examiner.com, cdn.trtk.net, ec.dstimage.disposolutions.com, welcome2.carsdirect.com, s1.card-images.com, update.alot.com, www.outsystems.com, www.drwmedia.com, cdn.taxact.com, cdn.taxactonline.com, cdn.200581.com, img.vxcdn.com, js.vxcdn.com, www.cloudwords.com, images.skincarerx.com, ssl.cdn-redfin.com, cdn.foxycart.com, ssl.booztx.com, p.typekit.net, use.typekit.net, cdn.thewatershed.com, b2bportal.disneylandparis.com, b2bportal.disneytravelagents.co.uk, assets.zendesk.com, a.cdnkic.com, s.cdnkic.com, cdn.cartrawler.com, secure.33across.com, static.teamtreehouse.com, www.edgecast.com (Error code: ssl_error_bad_cert_domain)

I am using revision 42.0, Frontier is my provider, switching search engines does not alleviate the problem. In the middle of a session my browser switches to "Untrusted Connection". From that point until I give up and try later I am unable to make any connection. The Technical Details says: Ixquick.com (or whomever) uses an invalid security certificate. The certificate is only valid for security.frontier.com (Error code: ssl_error_bad_cert_domain)

Sometimes I am given the option "I understand the risks" and sometimes I am not. I don't know if this is a Mozilla problem or a Frontier problem. Can you help, please?

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!
