    I've be trying to capture traffic from an website but Fiddler doesn't show any requests/responses. On the same website it shows only the part before login, but as soon as I try to capture inside the webapp it won't work.

    Btw, I tried to do the same task with Firebug and it worked, but I still want to get Fiddler working

    The most likely explanation is that you haven't enabled HTTPS decryption, or haven't configured your client 
    device to trust Fiddler's certificate.

    Can you provide more details? What website? Have you enabled HTTPS decryption in Tools > Fiddler Options?

    I think you might be right. I've enabled HTTPS decryption but I started getting errors like this http://i.gyazo.com/2e405763d34d6440c2cb4db8676dd61d.png

    It should work after fixing the certificate , but how to do it ?

    In Fiddler, click Tools > Fiddler Options > HTTPS. Untick "Decrypt HTTPS traffic." Click "Remove Interception Certificates." Accept all prompts to remove certificates. When the process completes, retick the "Decrypt HTTPS traffic" box and accept all prompts to trust the new certificate.
