I was wondering if I could use Fiddler2 on only some processes instead of all applications which use system proxy settings. I know there is a filter option in Fiddler2, but as far as I know, it only hides information and the traffic is captured anyway.
There is a "Any Processes" button on fiddler toolbar. Drag the icon to a window to show traffic from only that process. Click the icon again to cancel the filter.
This is the best and simplest way to filter by process.
Or, in File menu, don't check the "Capture Traffice" item. Then set proxy in your others applications which need to be captured by fiddler.
If you capture HTTPS, open the https config dialog(Fiddler Options >> HTTPS), you'll see a list box with these list items:
...from all processes
...from browsers only
...from non-browsers only
...from remote client only
Here is a video which shows you how to filter by processes in fiddler. Towards the end of the video, you can learn how to filter by browser or even the tab of a browser.

Steps (Fiddler 4.3x) -
Fiddler > Filters Tab
Use filters - check it!
Client processes : Show only Traffic from - check it! > Choose your process (a browser or tab in browser) from the adjacent drop down menu.
Actions button > Run filterset now - click it!
Done !
To use Fiddler for capturing traffic from a specific process/Application fiddler has provided a option - "Any Process"
Steps :
Open/Launch the application which you want to monitor.
Select "Any Process" option and Drag it to the you application.
Now you have restricted Fiddler to capture the traffic from a specific Process/Application.

HTTP/2 server push allows a server to "push" resources to the browser before the browser has actually requested them.
When using the network tab of the Chrome DevTools, how can I tell which resources were "pushed" vs. ones that were requested in the traditional way?
I know that I can enable the Protocol column in the network tab, and that shows some calls as "h2" which I assume means HTTP/2. But what do I look for to tell whether it was actually pushed?
Look for Push in the Initiator column. See image.jpg in the screenshot below.
Hovering over the Waterfall also shows a breakdown of the push-related activity.
I know that I can enable the Protocol column in the network tab, and that shows some calls as "h2" which I assume means HTTP/2.
Yes, this is correct. h2 stands for HTTP/2. As mentioned, the Protocol column is hidden by default. Right-click the table header and select Protocol to enable it. See Show more information for an example.
I have Firefox version 52.1. I cannot udpate to newer version, nor can I add plugins that people ordinarily install to address these issues.
I am calling some rest services that require communicating that these are POST request plus a couple of other things ordinarily communicated through hearder information.
What options do I have for adding these specific header requirements to my Firefox request assuming I cannot add plugins or upgrade to a newer version of the browser? Thank you.
Ok, so simply by opening the very basic developer tools (i.e. press F12), then executing the request (which will fail because it is missing header info), then selecting the network tab in the tool followed by the All within the Network frame, it shows the failure info. Then I can select the default method value (GET) in the table of the attempted request, it will open a frame of the right of the tool. This frame has a header tab whose frame allows you to modify the header by clicking the Edit and Resend button. Click that button and then add the additional needed header params. then click the resend button.
Another option is to use Postman. Especially when you're going to do this on a regular basis. I started out using just the browser like you, but it got pretty cumbersome, so I switched to Postman.

How to search through all the ajax responses in network tab in Chrome?
I want to do this is because it is difficult for a JavaScript developer to get to know which information is coming from which service call, especially if you are new to the project and business logic is not clear. Also, opening each service in a network tab and searching in responses of so many service calls is difficult and time consuming.
This has now been implemented on the Network tab. Whenever a search criteria is added, Chrome will offer searching through all headers and bodies.
More from offical doc,
Open the Network panel then press Command+F (Mac) or Control+F (Windows, Linux, Chrome OS) to open the new Network Search pane.
This is similar to another question this morning to search json responses. The solution is the same, star this issue this issue. Starring is triggered via the star icon in the far left area of the blue title are just under search.
Starring issues let's the developers know what people need. The more stars something has, the more likely it is to get worked on sooner.
Currently this functionality is not provided and extensions are unable to add this type of functionality since the network panel isn't extensible in this way.
In Firefox you can save all the responses as a HAR file and then search through the file in a text editor (Chrome truncates the responses).
Inspector of Microsoft Edge browser offer such feature. Useful when you need to search through traffic made by an HTTPS web site that Fiddler cannot inspect (like Facebook web site).
There doesn't seem to be a way to do this in Chrome or Firefox. My solution has been to use Fiddler, which does support it.
Edit: I believe this was working for all resources at the time of writing, but please see comments because people say it is not/no-longer working as expected.
As of Chrome version 91, if you want to search through all resources (not just AJAX/fetched resources), then you need to open DevTools and then press Ctrl+Shift+F to open a search box. If you just type into the "filter" text input then it only searches through the URLs, rather than also searching the contents.
In Fiddler I have many responses which I like to view raw. For each one Fiddler says "Response is encoded and may need to be decoded before inspection. Click here to transform."
I want not only the current one, but all responses to always be transformed. Anyone know how to set this? Rules->Remove all encodings does not do the trick.
If the goal is to remove compression during the processing of a session:
That's what the "Decode" button on the toolbar does.
That's also what Rules menu > "Remove all encodings" does.
If the goal is to remove the encoding after session processing is complete, select all of the sessions (CTRL+A) and use "Decode Selected Sessions" on the Web Sessions list's context menu.
It's very easy. Just click the "Decode" button on Fiddler's toolbar.
In Fiddler's Filters tab, I have "Use Filters" checked off.
I have no zone filter.
I have chosen "Show only the following hosts" and have added the host name that I want to show exactly as it is displayed in Fiddler's "Host" column in the Web Sessions window.
It's not working at all.
I have Fiddler set up to capture all processes.
I'd also like to get Fiddler to show a couple of different hosts
Any suggestions? thanks.
In Fiddler's Filters tab, I have "Use Filters" checked off.
->checked off? should be on.
I have chosen "Show only the following hosts" and have added the host name that I want to show exactly as it is displayed in Fiddler's "Host" column in the Web Sessions window.
->make sure you didn't add the 'http://' before it
I'd also like to get Fiddler to show a couple of different hosts
->just separate them with a space or colon.
good luck!
You should check the "use filters" checkbox.
In the "Show only the following hosts" textbox, type the names of the hosts separated by colon. If you have several similar hosts then you can use wildcards also(see below for an example).
