Firefox SECERRORUNKNOWNISSUER Fix Option 1: Run a Virus Scan If a virus is preventing the certificate from being detected, the error code may occur. Thus, running a virus scan for your entire Windows system could be helpful.

If you have recently updated to Firefox version 58, you may have noticed an annoying error code when visiting websites. ‘SEC_ERROR_UNKNOWN_ISSUER’ (Your Connection is Not Secure)isn’t all that common, however, after updating Firefox, you may start to see it more frequently, even on popular websites like Google.com. Thankfully there are a few simple ways you can fix the issue.

Although Firefox is the underdog in the browser market, it is one of the best browsers on the market. It’s fast, has a very clean interface, and uses significantly fewer resources than the top dog Chrome. As good as it is though, Firefox does have an annoying bug/error which affects a small percentage of users.

Error ‘SEC_ERROR_UNKNOWN_ISSUER’ has been around for quite some time, however, was very rare to see on Firefox 57, in most instances the issue was caused by the websites settings and not Firefoxes. Thankfully, regardless of the reason you are seeing this error message, there are a few different ways you can fix it.

How to Fix 'SEC_ERROR_UNKNOWN_ISSUER' & ‘Your Connection is Not Secure’ Error Messages on Firefox 58.

To remove this error from Firefox there are two different options available. The first is to add an exception for the website to your Antiviruses exception list. The second is to disable SSL/HTTPS scanning, again in your antivirus settings. Option one is by far the least risky and doesn’t open up a potential security flaw in your system. Option two, however, will save you having to add every website to the exception list. Before using either of these steps, make sure you have uninstalled Firefox and reinstalled it from scratch. If you are using a Firefox account it won’t take much time at all to set up your browser again.

Note: You can also try browsing the website using a New Private Window by right-clicking on the Firefox icon and selecting New Private Window.

How to Add Websites to Your Antivirus Exception List to Fix Firefox ‘SEC_ERROR_UNKNOWN_ISSUER’ & ‘Your Connection is Not Secure’ Errors.

This process will differ a little depending on the antivirus program you are using, however, the option should be under a very similar heading. Below you will find an example of how to add a website to Avast’s exceptions list. To begin open Avast, stay on the Status tab, then click Settings at the bottom of the page.

On the next page stay on the General tab and expand the Exclusions section using the drop-down arrow. Now simply change to the URLs tab and add the website you can’t get access to, to the list.

Note: Depending on the website, Firefox may allow you to add an exception directly from the error message. Simply click Advanced > Add Exception and manually add the website URL.

How to Disable SSL/HTTPS Scanning to ‘Fix SEC_ERROR_UNKNOWN_ISSUER’ & ‘Your Connection is Not Secure’ Errors on Firefox 58.

As we mentioned above, this isn’t the most recommended or safest solution, but it will get rid of the error on your browser. (Again these steps will vary somewhat depending on the antivirus software you are using). Below you will find an example of how to add a website to Avast’s exceptions list. Regina spektor soviet kitsch rar.

Open Avast, stay on the Status tab and click Settings at the bottom of the page.

Next, change to the Components tab and click Customize next to Web Shield.

On this screen stay on Main Settings and Untick the box next to Enable HTTPS Scanning. Once this is done, click Ok to save the changes. As mentioned above, if you can avoid using this method it is suggested, however, if you don’t want to change browsers and don’t mind the security risk, feel free to make the change.

On websites which are supposed to be secure (the URL begins with 'https://'), Firefox must verify that the certificate presented by the website is valid. If the certificate cannot be validated, Firefox will stop the connection to the website and show a 'Warning: Potential Security Risk Ahead' error page instead. Clicking the button, you can view the specific error Firefox encountered.

This article explains why you might see SEC_ERROR_UNKNOWN_ISSUER, MOZILLA_PKIX_ERROR_MITM_DETECTED or ERROR_SELF_SIGNED_CERT error codes on an error page and how to troubleshoot it.

Sec_error_unknown_issuer Firefox Fix For Mac Windows 10

During a secure connection, a website must provide a certificate issued by a trusted certificate authority to ensure that the user is connected to the intended target and the connection is encrypted. If you click the button on a 'Warning: Potential Security Risk Ahead' error page and you see the error code SEC_ERROR_UNKNOWN_ISSUER or MOZILLA_PKIX_ERROR_MITM_DETECTED, it means that the provided certificate was issued by a certificate authority that is not known by Firefox and, therefore, cannot be trusted by default.

If you get this problem on multiple unrelated HTTPS-sites, it indicates that something on your system or network is intercepting your connection and injecting certificates in a way that is not trusted by Firefox. The most common causes are security software scanning encrypted connections, or malware listening in and replacing legitimate website certificates with their own.In particular, the error code MOZILLA_PKIX_ERROR_MITM_DETECTED indicates that Firefox detected connection interception.

Antivirus products

Third-party antivirus software can interfere with Firefox's secure connections. You could try reinstalling it, which might trigger the software into placing its certificates into the Firefox trust store again.

We recommend uninstalling your third-party software and using the security software offered for Windows by Microsoft:

• Windows 8 and Windows 10 - Windows Defender (built-in)

If you do not want to uninstall your third-party software, you could try reinstalling it, which might trigger the software into placing its certificates into the Firefox trust store again.

Here are some alternative solutions you can try: Huey lewis best hits youtube.

Avast/AVG

In Avast or AVG security products you can disable the interception of secure connections:

1. Open the dashboard of your Avast or AVG application.
2. Go to Menu and click on Settings > Protection > Core Shields.
3. Scroll down to the Configure shield settings section and click on Web Shield.
4. Uncheck the box next to Enable HTTPS Scanning and confirm this by clicking .

   In older versions of the product you'll find the corresponding option when you go to Menu > Settings > Components and click next to Web Shield

See the Avast support article Managing HTTPS scanning in Web Shield in Avast Antivirus for details. More Information about this feature is available on this Avast Blog.

Bitdefender

In Bitdefender security products you can disable the interception of secure connections:

1. Open the dashboard of your Bitdefender application.
2. Go to Protection and in the Online Threat Prevention section click on Settings.
3. Toggle off the Encrypted Web Scan setting.

   In older versions of the product you can find the corresponding option labelled Scan SSL when you go to Modules > Web Protection

In Bitdefender Antivirus Free it's not possible to control this setting. You can try to repair or remove the program instead when you're having problems accessing secure websites.

For corporate Bitdefender products, please refer to this Bitdefender Support Center page.

Bullguard

In Bullguard security products you can disable the interception of secure connections on particular major websites like Google, Yahoo and Facebook:

1. Open the dashboard of your Bullguard application.
2. Click on Settings and enable the Advanced view on the top right of the panel.
3. Go to Antivirus > Safe browsing.
4. Uncheck the Show safe results option for those websites which are showing an error message.

ESET

In ESET security products you can try to disable and re-enable SSL/TLS protocol filtering or generally disable the interception of secure connections as described in ESET’s support article.

Kaspersky

Affected users of Kaspersky should upgrade to the most recent version of their security product, as Kaspersky 2019 and above contain mitigations for this problem. The Kaspersky Downloads page includes 'update' links that will install the latest version free of charge for users with a current subscription.

Otherwise, you can also disable the interception of secure connections:

1. Open the dashboard of your Kaspersky application.
2. Click on Settings on the bottom-left.
3. Click Additional and then Network.
4. In the Encrypted connections scanning section check the Do not scan encrypted connections option and confirm this change.
5. Finally, reboot your system for the changes to take effect.

Family Safety settings in Windows accounts

In Microsoft Windows accounts protected by Family Safety settings, secure connections on popular websites like Google, Facebook and YouTube might be intercepted and their certificates replaced by a certificate issued by Microsoft in order to filter and record search activity.

Read this Microsoft FAQ page on how to turn off these family features for accounts. In case you want to manually install the missing certificates for affected accounts, you can refer to this Microsoft support article.

Monitoring/filtering in corporate networks

Some traffic monitoring/filtering products used in corporate environments might intercept encrypted connections by replacing a website's certificate with their own, at the same time possibly triggering errors on secure HTTPS-sites.

If you suspect this might be the case, please contact your IT department to ensure the correct configuration of Firefox to enable it working properly in such an environment, as the necessary certificate might have to be placed in the Firefox trust store first. More information for IT departments on how to go about this can be found in the Mozilla Wiki page CA:AddRootToFirefox.

Malware

Some forms of malware intercepting encrypted web traffic can cause this error message - refer to the article Troubleshoot Firefox issues caused by malware on how to deal with malware problems.

In case you get this problem on one particular site only, this type of error generally indicates that the web server is not configured properly. However, if you see this error on a legitimate major website like Google or Facebook or sites where financial transactions take place, you should continue with the steps outlined above.

Certificate issued by a authority belonging to Symantec

After a number of irregularities with certificates issued by Symantec root authorities came to light, browser vendors, including Mozilla, are gradually removing trust from these certificates in their products. Firefox will no longer trust server certificates issued by Symantec, including those issued under the GeoTrust, RapidSSL, Thawte and Verisign brands. For more information, see this Mozilla blog post and this compatibility document.

MOZILLA_PKIX_ERROR_ADDITIONAL_POLICY_CONSTRAINT_FAILED will be the primary error, but with some servers, you may see the error code SEC_ERROR_UNKNOWN_ISSUER instead. If you come across such a site you should contact the owner of the website to inform them of the problem.

Mozilla strongly encourages operators of affected sites to take immediate action to replace these certificates. DigiCert is providing certificate replacements for free.

Missing intermediate certificate

On a site with a missing intermediate certificate you will see the following error description after you click on on the error page:

The website's certificate might not have been issued by a trusted certificate authority itself and no complete certificate chain to a trusted authority was provided either (a so-called 'intermediate certificate' is missing).
You can test if a site is properly configured by entering a website's address into a third-party tool like SSL Labs' test page. If it is returning the result 'Chain issues: Incomplete', a proper intermediate certificate is missing.You should contact the owner of the website you're having troubles accessing to inform them of that problem.

Self-signed certificate

On a site with a self-signed certificate you will see the error code ERROR_SELF_SIGNED_CERT and the following error description, after you click on on the error page:

A self-signed certificate that wasn't issued by a recognized certificate authority is not trusted by default. Self-signed certificates can make your data safe from eavesdroppers, but say nothing about who the recipient of the data is. This is common for intranet websites that aren't available publicly and you may bypass the warning for such sites.

Bypassing the warning

If the website allows it, you can bypass the warning in order to visit the site, even thought its certificate is not being trusted by default:

1. On the warning page, click .
2. Click .
