"Target Any Process" feature no longer working with Chrome. It used to work but no longer works specifically with Chrome. Still works with other processes. Capturing still works with Chrome as long as I am not using the "Target Any Process" feature.
It would be highly useful if there was a "URL splitter" tool added, perhaps as a drop-down entry in the TextWizard, which takes a long-form paramaterized URL and splits it into a line-separated list of individual parameters (and can go the opposite way direction as well).
The "WebForms" subpanel already does this, albeit there's no manual ability to choose what URLs this can be done to ...as far as I'm aware.
Once a program has been "Filter now"ed via the context menu, if that filter is later deleted from down bottom, that program can no longer be "Filter Now"ed again; nothing happens.
It's as if program filtering is only given one opportunity to be "Filter Now"ed. Once that's happened, even if they filter gets deleted, the program isn't given another opportunity to be Filter Now'ed.
I've attached the raw HTTP response, copied directly from Fiddler. At lOperations.lRecords, you'll see that there are 2 records (arrays) and that each record contains 6 items, the last of which is an array. However, when I view the resonse using the JSON filter, the second of these arrays appears to contain only 5 items. I'm sure that the bug has something to do with the fact that the sub-array in the second array is an empty array, but it should display as an empty array, not as if it weren't there at all.
1-st of all, thanks for the Fiddler!
I'm using the custom font size set under the Fiddler options (Windows OS), but its not respected during the params editing.
see attached screenshot.
I use the request LogRequests history to save requests, so that I can replay them when needed. Every month or so when my machine is restarted for an update and if Fiddler is opened, the history is corrupted.
I need a way to either save off certain requests like I can in Postman, etc, or I need Fiddler to have reliable restore points for the history so that the entire history is not corrupted so often.
Please fix or add a feature to address this -
HOSTS in fiddler shouldn't change SNI info when Decrypt HTTPS traffic is enabled
When Decrypt HTTPS traffic is enabled and use HOSTS in fiddler, SNI should be keep the same as request, instead of use the one from HOSTS(removed when use IP, or rewrite when use another HOSTS)
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
Allow to search / reuse requests from history in a more efficient way 1. Add column [Date] or [Date and Time] to history, so one can look for a request that was used at a given date / time 3. Allow to sort by request Url, date / time 4. Allow to group by request urls: If there are several requests with the same url, provide the option to group / ungroup them 5. Add column [Result] with the result code for each request, so that one can now which request to use (for example, one needs a request that gave a 404, or only 202s) 6. Filter history by request type (GET, PUT, ...), url content (example: search for "/admin/ ... etc"), date / time
When my machine restarts before Fiddler is closed gracefully, Fiddler opens back up with an error saying that my capture saz is corrupt and cannot be opened.
This is a pain as I have to then manually rebuild any requests that I need.
Fiddler should have savepoints or some way to prevent it from losing all my LogResuest history whenever Fiddler is forcefully shut down
If you try to launch two instances of Fiddler/FiddlerViewer at the same time, you hit a sharing violation.
This file needs to be read with the correct sharing flags set.---------------------------
I recently am having an issue with MS Teams while running fiddler. MS Teams keeps giving disconnect errors. That's when I noticed that fiddler it proxying it's traffic even though I have filters set to "Show only the following Hosts", and teams.microsoft.com are not included in the hosts. I also notice other items in my sessions list that are not in my list of hosts so what is going on?
I don't really want to post my list of hosts publicly. If you need them, please let me know and maybe I can email them to someone.
Please consider installing a desktop shortcut or start menu shortcut to launch Fiddler viewer (instead of fiddler to listen and capture traffic). This will help folk that want to review fiddler traces from others without launching Fiddler and interfering with locally running apps that misbehave due to Fiddler intercepting traffic by default on launch.
i realize I can create my own shortcut using "fiddler.exe -viewer". But I want to write troubleshooting guides to engineers that are new to both the technology they are learning and Fiddler/HTTP traffic analysis in general. Having two shortcuts created will make it easier to write instructions where we can advise folk to just launch shortcut to viewer to import a session or previously made fiddler saz file from someone else.
I am using Fiddler for 6 months and I found it really nice and simple to understand and get the required information, but one feature in which fiddler is lacking is the NIC information although with fiddler we get the Source and destination IP, port, MIME type, TLS/SSL versions etc but if we get this NIC information it will be complete solution for Web debugging.
I am getting the following error in fiddler and without Capture HTTPS CONNECTs it works, also in the Protocols I have enabled: <client>;ssl2;ssl3;tls1.0;tls1.1;tls1.2
fiddler.network.https> HTTPS handshake to <domain> (for #6) failed. System.Security.Authentication.AuthenticationException A call to SSPI failed, see inner exception. < The message received was unexpected or badly formatted

When I go to File | Save | All Sessions it defaults to a directory (that is not where I want to store the debug information I collected).
I store all problems I am working on in a different directory structure. When I go to SAVE my debug session I would like to set the Default directory (structure) where I save all my other documentation for problems I am working on. Having to "re-find" my documentation folder multiple times in 20 minutes of saving multiple debug sessions is tedious and non-productive.
I suggest a user preference that has these options:
Set default directory to: .......... (It will always open to here when a SAVE is done)
Follow Last SAVE directory: (Check box) This will open whatever directory location you last did a SAVE to
User Fiddler's Default Location: (Check box) This is like a "Reset" to Fiddler's default location.
When loading the SAZ file, the requests are ordered incrementally based on the order they were saved in.
For example, a Fiddler session was sorted by URL and then saved to SAZ. When the file is loaded, the requests are still sorted by URL but the original index numbers are lost and the requests are numbered incrementally as per this sort. This means that it is not possible to sort the session back to the original linear order by clicking on the index column (#) as it was possible to do before the save/load.
I've seen that the original index is saved in the Comments column. This is only a partial solution because:
1. When sorting by this column, a lexical sort is performed meaning the sessions would be numbered: 1,10,100,101,11,12..19,2,20,21 etc...
2. If the request had a comment associated with it, this overrides this feature and the original index number is lost.
Also, I know it's possible to sort by ClientDoneRequest as a good approximation but it obviously doesn't recreate the original order.
It would be beneficial to keep the original index numbers (even including the gaps between them) as there is information there that shouldn't be lost when saving.
As always thank you for your work on this wonderful product.
This bug occurs in both Fiddler and Fiddler Everywhere so you may want to take a look.
The system I'm running on is Win7x64 with latest patches loaded.
Note that when Fiddler/Fiddler Everywhere is not loaded, I can access this website normally.====== Message from Fiddler v5.0.20204.45441 for .NET v4.6.1 Built: 2020-11-03 ======
A screenshot of the error is provided, I think there are extra characters in the form, these should not appear, it seems to be caused by a decoding error. Note that the transfer method "transfer-encoding: chunked".
