Firefox Support Forum

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)

Is there a way to send a request or verification ticket to either the company's website or Mozilla for SSL certification? Like, sending a link to DigiCert Inc. or Google Inc. Authority? I want to be sure that my connection to the website is private and secure. Furthermore, if the web page does not provide an SSL certification or verified website approval, would the passwords that I saved through Mozilla Firefox password manager be compromised or will they be secure even visiting a website that has no SSL certificate or verification? Please answer these two questions as soon as possible. Thank you.

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.

How can this be fixed?

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)

Hello, Is there a way to install two certificates on a Mac for all users? Currently I have to login on a Mac, using several user accounts that use this computer, and then manually import the two certificates for each user profile for a single Mac. Is there a way to automate this process? Every Mac in my environment has at least 3-5 user profiles and I have to login 3-5 times to add these two certificates. Also, if a new user logins for the first time on this Mac, I have to manually add the certificate as well.

Thanks!

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 am trying to download a Certificate under View My Certificates. There is none there. I get a prompt in the process that says:

This personal certificate can't be installed because you do not own the corresponding private key which was created when the certificate was requested.

How do I find or own the corresponding private key?

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.

The QA team at my company performs tons of upgrade testing and, on each upgrade, the software generates new self-signed SSL certificates on our server. After each upgrade, they access the site with Firefox and need to make an exception for the self-signed cert (on the "Your connection is not secure" screen).

After about 10 upgrades (and accepting the new self-signed certs), Firefox (46.0.1) begins to load the page more slowly. Each time after that becomes exponentially slower: - 11th time takes a couple of seconds to load - 12th takes 10+ seconds - 13th takes 30+ seconds, and finally; - 14th just doesn't load (or eventually does but I gave up after a few minutes)

This can be fixed by deleting all of the Authorities from the self-signed certs (not the certs themselves). So, I'd go to Preferences > Advanced > Certificates (tab) > View Certificates > Authorities and then delete the authorities related to the self-signed certs; the actual certs aren't removed. This fixes the problem until the next 10th upgrade is performed.

This also affects Firefox 45.0.1 - though is considerably worse than 46.0.1; it's unusable after 8 upgrades. When I say "unusable" I mean that our site doesn't load, all other websites load and work correctly.

This affects Firefox on Mac OS X, CentOS 7/6.6, and Windows 7. The only plugin installed is Firebug

Any thoughts as to why this is occurring?

Thanks in advance for the help.

I just started having logging on to my ADMIN part of my website and we have installed a SSL Certificate in February 2016. I have to use MicroSoft Internet Explorer to get into my administration side of my website. Here is the "error message" I am receiving: "Secure Connection Failed" The connection to pertneubees.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.

Please let me know what I can do on my side or is there a FireFox setting I could easily perform to allow sign in to my ADMIN site?

Thanks.

I am on Macbook Air canoot access some sites that I was able to access even a couple of hours ago. The problem seems to be both with Firefox and Safari. One rules I noticed is that I can access sites with valid certificates and cannot the ones without. Any suggestions?

I'm attempting to download this file but it has an Error code: SSL_ERROR_BAD_CERT_DOMAIN https://files.vagrantup.com/precise32.box

There is no option to add an exception.

The steps I have tried to fix this are: 1) Disabled all plugins and addons 2) Pasted the URL, domain name (both the issuing website and the domain of the URL) in chrome://pippki/content/exceptionDialog.xul (with and without clicking "Get Certificate") 3) Manually entered the above details into: Tools > Options > Advanced > Certificates > View Certificates > Servers > Add Exception (with and without clicking "Get Certificate") 4) Deleted the file cache 5) Disabled and then removed anti virus software and firewall 6) Emptied my hosts file 7) Renamed cert8.db 8) Created a new profile 9) Removed and reinstalled Firefox

I'm running FF 47.0

Please let me know if I should file a bug.

Is there a way to have Mozilla trust the local Windows user certificate store? We have deployed user certificates as non-exportable so the only way to get them is to reference the Windows store directly. Exporting them and importing them into Mozilla is not an option.

We use SSL inspection and for it to work we have to import our organization's Root CA cert into the Firefox cert store. I've confirmed this works fine in Firefox 47 and 48 as well as older versions, but has stopped working in Firefox 49.0

Oddly enough I am still able to import certs in Firefox 49.0 x64 client, just not in the x86 client. Tested Firefox 50b4 and still having the same issue.

When I navigate to one of our internal SSL-enabled websites that uses a self-signed certificate, 49.0.2 does nothing upon clicking CONFIRM SECURITY EXCEPTION when PERMANENTLY STORE THIS EXCEPTION option is checked. Click on that button does nothing and it is impossible to navigate to the site until the option is deselected. I've reinstalled 48.0.2 and the issue disappeared.
