  • 0

i’ve recently bought a comodo ssl certificate with a 256bit encryption as a advice of my friend who uses that in his server and installed it to my server with following the instructions from google exc.

After that i’ve changed all the links with http to https, and that fixed the problem which is
Continue to This Website (not recommended) within Chrome, IE and Safari.

However while it seems like okay in my firefox, i’ve noticed that in my friends’ firefox browser, the problem still continues and if they dont select okay, all of the css files exc are being gone ( i think its because not loading the css files exc because browser thinks that its dangerous ) anyway, but everything is good with their chrome, safari and ie too..

After that i’ve checked all of the firefox versions with browsershots.org and it has also not showed me any erros or continue to this website error exc.

After that, i’ve asked my hosting provider that why that can happen, and they replied that this is a normal process, wait for 10-15 days and that will be good. But i’m not sure whether they said the truth or not.

PS : I dont even think that this can be a problem for any of the browsers, but can firefox think that with seeing the http there, can it be the reason ?

If you can help me with this problem, ill be glad

Thanks

    There is a problem with this website’s security certificate. The
    security certificate presented by this website was not issued by a
    trusted certificate authority.

    Security certificate problems may indicate an attempt to fool you or
    intercept data you send to the server. We recommend that you close
    this webpage and do not continue to this Web site.

    This has nothing to do with bad links or mixed content, rather, it has to do with certificates themselves.

    You could test your site with Qualys SSL Labs’ SSL test, which is usually more comprehensive than others.

    Assuming that the certificate you’ve installed is indeed the correct one (you can check this in ‘Add Exception…’ and ‘View…’ to view the certificate details at that they are indeed those you see in your certificate), a few possible causes come to mind:

    • The CA you’re using isn’t recognised by the browser. This is quite unlikely since Comodo is very common.
    • The certificate chain you’ve installed on your server isn’t in the right order and/or doesn’t have all the intermediate CA certificates, if any.
    • This particular browser had visited a site with this name with another cert and had put a specific exception. This may conflict with the CA-based verification. Just in case, go into Options -> Advanced -> View Certificates -> Servers, and check that the server isn’t on the list. (You can also check that the CA you’re using is in the ‘Authorities’ list, but it’s likely it is.)
