This will make other browsers (like Chrome), and Windows apps such as Discord, also trust the proxy (Fiddler). This isn't strictly necessary, but if it's not done, you won't be able to use Chrome/Discord/Etc while Fiddler is running and intercepting traffic.Important: Add exclusions to your proxy: In Fiddler, go to Tools->Options->Connections, and add the following into the "Bypass URLs that begin with..." field:;discord.com; discordapp.com; netflix.com; *.discord.com; *.discordapp.com; *.netflix.com; *.discordapp.net; discordapp.net; *.google.com; google.com; *.gmail.com; gmail.com; *.youtube.com; *.gstatic.com; *.cloudflare.com; *.googleapis.com; *.jquery.com; *.googlevideo.com; support.neopets.comDownload the neopets folder in this projectFind fiddler installation path (usually C:\Users\YOUR_USERNAME\AppData\Local\Programs\Fiddler or C:\Program Files\Fiddler), create a folder named "neopets" and extract the downloaded neopets.zip files into it.

You can remove this certificate later via Windows Certificate Manager (certmgr.msc->Trusted Root Certification Authorities->Certificates). The name of the certificate is DO_NOT_TRUST so that you're well aware it's a local certificate, and not from a trusted Certificate Authority (CA). It is safe to trust this certificate, BUT the implications are that you will not see any genuine certificate errors from websites, so you should keep Fiddler closed when you're not using it, and you should remove the certificate if you stop playing Neopets games.Fiddler seems to

The time has come for Fiddler to say goodbye to .NET 3.5. Our usage statistics currently show that less than 3% of our users are using .NET 3.5, and so we can no longer justify the effort needed to keep all new Fiddler versions running on .NET 3.5. We are still going to keep the most recent (at the time of writing) .NET 3.5 version in the Fiddler installer, and it will be automatically chosen for installation on machines that have no higher version of .NET installed. While you're welcome to keep using it, this version is not going to get updated from this point on. As time passes it is going to get less and less useful, and at some point in the future we will remove it completely. So, to sum up, in order to get updates to Fiddler from now on one should have at least .NET 4.0 installed. .NET 4.0 replaces .NET 3.5 as the minimal supported .NET version for Fiddler. FiddlerCore FiddlerCore will follow suit with Fiddler. The .NET 2.0 and .NET 3.5 builds will remain in the installer but will cease to get updates. The .NET 4.0 framework is going to be the lowest .NET version that will continue to receive FiddlerCore updates. Fiddler Add-ons At present the vast majority of Fiddler add-ons are compiled against .NET 3.5. They will keep on working on the new versions of Fiddler the same way they work on Fiddler for .NET 4.0 now. We will release .NET 4.0 versions of the add-ons that we maintain since it is now safe to do that. All add on creators are welcome to do that, too, and benefit from the features offered by .NET 4.0. In the future we will remove the dependency between the add-ons .NET version and the

Answered on 17 Jul 2014, 12:35 AM Hi, Stephen--I don't really understand your question. Fiddler is non-malicious, if that's what you're asking. Generally speaking, Fiddler shows traffic from your local computer only, not from "embedded devices" so it sounds like maybe you've set some other configuration? If you were to run Fiddler on a public IP and allow arbitrary connections, then Fiddler could serve as a proxy for anyone who chose to use your IP as a proxy, but you'd see their traffic inside Fiddler itself.If you have a PCAP of the traffic in question, please feel to email it to me using Help > Send Feedback inside Fiddler and I'll have a look upon my return to the office.Regards, Eric Lawrence TelerikCheck out the Telerik Platform - the only platform that combines a rich set of UI tools with powerful cloud services to develop web, hybrid and native mobile apps.
