Hello,

I updated Fiddler today and the fonts are way too small on all of our devices. I have observed numerous complaints regarding this issue by others on the Internet.

I just learned on this forum that you do not support downloading a previous version. Too bad, but I understand your policy.

Hope this issue gets addressed soon.

Regards...

As you can see above, im using C# and its returning a Handshake Error (sslStream.AuthenticateAsClient(host)).

This is ONLY occuring if I connect via proxy to ipv4:8888 (Fiddler's Proxy).

If I were to close off fiddler and use another proxy, or no proxy at all, it would work fine.

Honestly clueless as to why its occuring. My library had 1 other connection issue due to incorrectly syncing a stream.read for a statusline check causing fiddler to show a red/yellow icon (https://i.imgur.com/VSSRShi.png) but I sorted that out.

Now im just trying to figure out why this is occuring.

Hi all,

I wanted to upgrade Fiddler to the latest version...

The automatic upgrade failed so I deinstalled the current version and now I'm getting an error message: "Uninstalling the currently installed version of ... failed" .

I cleaned up all the folders and the registry, rebooted, but it still won't install :'(

Thanks for your help!

hi respect for fiddler, i am from russia

subj, yes win xp base not support tls 1.2, only third party libraries supoport tls 1.2 on win xp (curl, openssl)

log from fiddler

HTTP/1.1 200 Connection Established
FiddlerGateway: Direct
StartTime: 07:57:56.679
Connection: close

fiddler.network.https> HTTPS handshake to 38.is-mis.ru (for #47) failed. System.IO.IOException Неожиданный EOF или 0 байт из транспортного потока.

I have a machine setup to run automated tests. I have some software, including Fiddler running as scheduled tasks on start up without user required to log in. I can see tests passing, which means traffic goes through Fiddler, as they would fail otherwise. When I log in to that machine, I can see in Task Manager Fiddler running as background process.

But nowhere I can see the traffic. Fiddler is running as background process and I can't find the folder where it stores temp files. I have also tried setting autosave to a file every 5 minutes. And while it works when I run fiddler in UI, no sessions are saved when it runs as background process.

I trying fiddlerCorde in a winform application. I like to capture traffic only for one domain and use filter too but when i surfing to other domain it increase memory used by the application. Is there any solution for purge fiddlercore sometimes?

best regards

Hi,
   I am accessing my visual studio project that resides on my laptop from my android phone. Most of it works but i have a java script file called "<script src="~/Scripts/mbsa_js.js"></script>" that shows up in fiddler with a 404. when i access the same file using visual studio, i get a 200. funny thing is that it accepts  "<script src="~/Scripts/mbsa_js.js"></script>" at one point, but in all other calls during this same fiddler process, it shows this  "<script src="~/Scripts/mbsa_js.js"></script>" file it shows 404. 

This gets weider because when i make up a javascript file name that does not exist like "<script src="~/Scripts/mbsab_js.js"></script>" , "mbsab", fiddler shows up as 200. but,as stated, this file name does not exist, how could fiddler show it as 200 instead of 404??

thanks for any advice and help.

I'm trying to write a response inspector, and after trying numerous things, I can't get it to appear on the Inspectors tab.

I've tried this basic test, and it doesn't seem to get loaded into Fiddler:

I've compiled this against Fiddler 4.5.0.0 and 2.5.0.0, and tried loading it into both. Neither seems to work.

I know that my dll is being loaded by Fiddler though. If I add this to the DLL, my Message Box appears while the application is loading.

I've even tried compiling / loading inspectors I've found on codeplex, but none of them seem to work.

Any help would be greatly appreciated.

hello all ,

  on my mac, I was not able to see fiddler capturing any web traffic. Do i need to set up some thing ?

I checked some other threads, and none are really helpful

I am trying to figure out if the Autoresponder can block a call based on not only the URL but the information in the header so that I can target specific calls from a given url instead of all calls for a given URL. 

I am having difficulty figuring out if its possible and if so what syntax for the rule I might use.

Thanks
