access to addons.mozilla.org is blocked in firefox but not in chrome
I want to use an addon which only is available to firefox. So I've installed firefox and tried to install this addon, but when going to the addons.mozilla.org I get an error SEC_ERROR_UNKNOWN_USER with no possibility to pass this by installing a certificate. When using chrome to access this page, there is no problem, but I can't download the addon as a file.

What certificate chain do you see in Google Chrome if you open the Details tab (second screenshot)?
If there is a root certificate that some filter software might be adding this certificate to the Windows certificate store. Firefox uses its own certificate store and won't see and use this root certificate. You would have to export this root certificate (SVB Root CA) in Google Chrome and import this certificate in the Firefox Certificate Manager.
- Options/Preferences -> Privacy & Security -> Certificates: View Certificates
You can find the Certificates section at the bottom of the "Privacy & Security" page or use the search bar (certificate).
When prompted set the trust bit to use the certificate to "Trust this CA to identify websites.
Note that you should never set any trust bits on an intermediate certificate when prompted. Trust bits are only required for trusted root certificates and should never be set on an intermediate certificate.

Who is the issuer of the certificate?
Can you please provide more detail about the issuer of the certificate?
- click the "Advanced" button show more detail
- click the blue SEC_ERROR_UNKNOWN_ISSUER message to show the certificate chain
- click "Copy text to clipboard" and paste the base64 certificate chain text in a reply
If clicking the SEC_ERROR_UNKNOWN_ISSUER text doesn't provide the certificate chain then try these steps to inspect the certificate.
- open the Server tab in the Certificate Manager
- Options/Preferences -> Privacy & Security -> Certificates: View Certificates -> Servers: "Add Exception"
- paste the URL of the website (https://xxx.xxx) in it's Location field.
Let Firefox retrieve the certificate -> "Get Certificate"
- click the "View" button and inspect the certificate
You can see detail like the issuer of the certificate and intermediate certificates in the Details tab.

That is a weird certificate issued by a proxy from the Sociale VerzekeringsBank (SVB_subCA_cpproxy, emailAddress=ICT.Verbindingen@svb.nl)
You can check the connection settings and make sure that you aren't using this proxy.
- Options/Preferences -> General -> Network: Connection -> Settings
If you do not need to use a proxy to connect to internet then try to select "No Proxy" if "Use the system proxy settings" or one of the others do not work properly.
See "Firefox connection settings":
I've tried every other connection setting. The only setting where I get a connection is the one 'Use the system proxy settings', and that gives me the SEC_ERROR_UNKNOWN_ISSUER error.
What certificate chain does Google Chrome show if you click the padlock?
No proxy should normally work unless there is some filter software or malware active that blocks internet access.
Boot the computer in Windows Safe mode with network support to see if that has effect in case security software is causing problems.
save mode is not an option as I'm working with a virtual desktop. Made some screenshots from the certificate in chrome on addons.mozilla.org
You can see that the issuer of the certificate is some kind of proxy.
You can check the connection settings.
- Options/Preferences -> General -> Network: Connection -> Settings
If you do not need to use a proxy to connect to internet then try to select "No Proxy" if "Use the system proxy settings" or one of the others do not work properly.
See "Firefox connection settings":
None of the settings work.
