HTTPS Problem and Images

[Miguel]

Hi guys,

I'm using FiddlerCore with VB.Net as I have to manipulate some pages in my company.
The problem is its acting weird with the HTTPS and most of the images in the webpages doesn't load.

Here you have the code I'm using right now:

Here you have a screenshot of the error:

I don't know why this happens as I have the certificate in the trustable:

What am I doing wrong?
Thanks for the help.

Hi, Miguel--

Firefox is the only browser that does not use the system's list of Trusted Root Certificate Authorities; instead it uses its own list. Please see http://blogs.telerik.com/fiddler/posts/13-04-01/configuring-firefox-for-fiddler for details.

Thanks Eric.
I see the problem with FireFox but I must do something automaticly as I'm configuring a large network.
Is there any way to trust the certificate in FireFox without going to all the computers in the network?
For example in FireFox I can change many things in the prefs of the firefox.
Is there a file in FireFox that I can edit to acomplish this?
Thank you.

Hello, Miguel-- 

Mozilla offers a command-line utility that can be used to update a Firefox User's Trusted Root store; it's non-trivial, but there are a number of guides on the Internet; for example: http://community.spiceworks.com/how_to/show/15158-firefox-trust-a-local-certificate-authority-for-all-users-and-computers
