This is a feature that's present in both the Firefox and Chrome dev tools, and it's incredibly useful. Fiddler is already great, and that would make it so much better :-)

I find having Capture on when you start Fiddler a pain since almost always one of the first things I have to do is turn it off. I'd like the option to just have it off on startup.

Not much more to say. Fiddler on Windows is absolutely awesome, but nothing comes close on Max OS X.

Please, please, please offer a native Mac OS X version. I'd hiply pay 4100 or more for it. I'd even pay that for an annual subscription.

When Telerik first acquired Fiddler, the community was afraid that Fiddler would become a paying tool. Telerik made an important statement: "Further, we have learned from the mistakes of others who have acquired free tools only to turn the tables on the developer community and monetize them at a later date." (source: https://www.telerik.com/about/press-releases/2012/09/10/telerik-announces-the-acquisition-of-fiddler).

Recently, Telerik asked Chocolatey, a widely used Windows package management platform (https://chocolatey.org/) to remove Fiddler from the packages list.

Whatever the reasons are, as a Chocolatey and Fiddler user, I am disappointed by that move. I am managing multiple machines, and Chocolatey helps me synchronize and accelerate new setups. Telerik just asked me to force manual installation of Fiddler, as well as manual upgrade (no, I don't want/need as many auto-update software as I have installed software). I see no value in doing so, except maybe forcing user registration (which is monetizing and breaks their promise) or for some legal reason.

I would kindly ask Telerik to take a stance on what was communicated to the community, and allow Chocolatey to provide an easier way to get your tools installed on more machines.

I'm filing this as a bug, since it was working, and it now is broken for me.

I'm using v5.0.20181.13826 for .NET 4.6.1.  I just upgraded today.  I have a 4k display running at 3840 x 2160.  I have the font scaling set to 200%.  The previous version of Fiddler worked with these settings.  I accepted the update when prompted today, but the Fiddler UI is no longer scaling the font.  Many of the menus are inaccessible or unusable.

I set my resolution to 1920 x 1080 with no scaling and the Fiddler UI was accessible.  I was able to access the menus and set the Fiddler font to 16, and returned to my regular 4k display settings.  Most of Fiddler was readable under this setting, but several areas don't appear to acknowledge this change.  Screen shots attached.

I downloaded FiddlerSetup.exe today and I can't get it to install. When I run the executable nothing happens. Even when I right click and run as admin. I successfully installed FiddlerCap as a test but not really what I need. I have full admin rights to my Windows 7 workstation. I even tried a reboot but no luck.

Tools > Fiddler Options > HTTPS.

Click Reset All Certificates.

Result: The "Ignore server certificate errors (unsafe)" box is automatically ticked.

This is a significant security vulnerability.

I am not sure if it is possible or not but it would be great to be able to use Fiddler on Mac too. Mac users have very few and expensive choices when it comes to proxy tools.

When Fiddler builds were moved from the dev's Windows PC to the Jenkins build server, one consequence is that the line-endings changed from Windows (CRLF) to Linux (LF).

This turns out not to affect the .dat files in the \ResponseTemplates\ folder (presumably due to the .DAT extension) but it DOES affect SampleRules.js, the file used as the default script if the user hasn't modified it.

This is very bad in the event that the user has Notepad as their script editor (and it is the default) because Windows does not respect bare LFs and thus it shows the entire script on a single huge line.

If fiddler was to honor the preference setting, people would have more faith in the correctness of the coding.
