Once I had gotten Fiddler to run (had to tell Mono to run in 32 bit mode) and I had re-created the settings.txt file, I received this error when trying to capture traffic: Fiddler/FiddlerAttach.applescript:7:87: execution error: /bin/sh: USB,127.0.0.1,8888,on,127.0.0.1,8888,on,0,0,off,0,0,off: command not found (127)
When the PDFView Inspector is installed (v18.104.22.168, whose public override int GetOrder() method returns 500), the Response Inspectors are rendered out of order, such that the Headers/Transformer inspectors are not at the front of the list.
There are some Files, fiddler needs write privileges: rm: cannot remove '/opt/fiddler/listeningProcess.txt': Permission denied rm: cannot remove '/opt/fiddler/gsettings.txt': Permission denied rm: cannot remove '/opt/fiddler/proxiesFromInterfaces.txt': Permission denied ... If this file is stored with the exe file, it is not possible to install fiddler in /bin or /opt and run without root privileges. I think it would be good to locate that file in the users home folder or in /tmp.
Sometimes,I need to know response json node's count,but I can only paste it into the json editor to see the quantity. Please check the pictures in the attachment.
I'm using Fiddler v4.6.20173.38786 (Built: Friday, September 15, 2017). When I click on the Customize Rules menu entry there is a message box that says "Unable to load Fiddler for code-completion support". After I click OK to that the Fiddler script editor will open normally.
Please package Fiddler with Homebrew Cask (https://github.com/Homebrew/homebrew-cask) , or at lease permit them to distribute the binary. Currently they are concerned about distributing Fiddler (https://github.com/Homebrew/homebrew-cask/pull/41374) .
Fiddler swaps out the real proxy settings for localhost when in use. When you disconnect or close it, it restores the proxy settings. However, if the system crashes or power fails while Fiddler is in use, upon rebooting the real proxy settings are of course missing, they're still set to localhost. I would expect that if were to then run Fiddler, it would find those proxy settings again so that if I run Fiddler and close it again, my original proxy settings would be restored. Sadly this doesn't happen so in this scenario I have to manually set up my proxy settings again. Can this be implemented?
request first line should be relative path,not be fullpath,it makes some troubles if server need relative path from head whether url.
I want to set the maximum session count to keep. Add some option in the configuration like "Max sessions to keep" so I can choose it from the menu "Keep sessions". Right now maximum session count I can choose is 10000 but it's too small value for me.
Office365 capturing stops when access token expires, blocking office refresh token? After 1 hour the access token expires and from that point on Outlook (office365) just starts getting 401 unauthorised responses and outlook stops working (don't get this when fiddler is not running). Other people on forum also saying they have seen the same issue.
I unchecked the "check for updates" box for a reason. It's just too much overhead and interrupts my productivity to have to stop and deal with an update before going and debugging the thing I'm working on. Even if the version is old, I'd rather just keep working than be interrupted.
HTTP/2 has been a standard since mid-2015. All major browsers support it, but adoption is slow because there no good debugging tools. I want to take advantage of pipelining, server push, etc that comes with HTTP/2 which makes it easier to adopt packages like gRPC. Having a good debugging story (both capture as well as insertion / modification) would make this more possible
Today, CONFIG.sDefaultBrowserExe and sDefaultBrowserParams are internal, default to Internet Explorer and they don't seem to be controlled by preferences. There should be a preference like fiddler.ui.toolbar.BrowserList.Default and fiddler.ui.toolbar.BrowserListDefaultParams that allows override.
In order to debug a website served on localhost by IIS Express you need to use localhost.fiddler to get traffic to show up in Fiddler, but if you use HTTPS you'll first get a warning that the certificate name does not match and you have to manually confirm this connection. This is generally a good idea, but in the case of localhost and localhost.fiddler I think this warning should not be shown, as having to use localhost.fiddler is simply a technical restriction that Fiddler should know about...
I accept your update and get to the install part and Windows 10 tells me that the update has an invalid certificate (or something).
