Firefox gives a site not trustworthy error message for my website on some computers. I am not able to duplicate this error message and am able to browse the site immediately. The Site is fine on IE and Chrome as well. Is there a way to correct this problem?

Is this an SSL certificate problem, or the red phishing/malware alert?

(1) If a user has visited any part of your site using SSL, the in-URL-bar autoFill feature turned on in Firefox 14 may cause Firefox to suggest HTTPS for other parts of your site that you did not set up for SSL access. More info on this issue: redirecting to https.

(2) Firefox frequently downloads an updated list from Google SafeBrowsing which on Windows 7 you can find here (to check the timestamps):

%USERPROFILE%\AppData\Local\Mozilla\Firefox\Profiles\your_Firefox_profile\safebrowsing

If your site has ever been in the list, perhaps some users are not getting the current one?

You can inspect the certificate chain via a site like this:

If there is a missing intermediate certificate then you need to install this certificate on the server.
