Is there a way to change cert type base on scenario

[Ryuu]

I have a problem with cert while using fiddler with android and I finally found the best solution. Change cert to generated by plug-in fiddlercertmaker.exe. By the way, anything in window such as Firefox browser fail to work properly with this type of cert. I already trust install and all. Can I set the system to use original fiddler cert when I use windows's process e.g. Firefox, or specific domain. Even by scripting in Fiddler Script, any solution is fine that I can use fiddler with browser too if solution exists.

 

Some website is accessible but it completely not in session list table, some of them cant access at all.

This is the whole error text (facebook):

Did Not Connect: Potential Security Issue

Firefox detected a potential security threat and did not continue to www.facebook.com because this website requires a secure connection.

What can you do about it?

www.facebook.com has a security policy called HTTP Strict Transport Security (HSTS), which means that Firefox can only connect to it securely. You can’t add an exception to visit this site.

The issue is most likely with the website, and there is nothing you can do to resolve it.

If you are on a corporate network or using anti-virus software, you can reach out to the support teams for assistance. You can also notify the website’s administrator about the problem.

Hi Ryuu,

 

Indeed, to enable the Android capturing, you need to switch the default certificate generation to Bouncy Castle (as pointed out in this documentation section). The default certificate generator won't work on most mobile devices so no other solution is applicable at this moment.

As a side note, the Fiddler Everywhere application is using the proper certificate generator by default.
