What is the name of the IE plug in that someone can download (I think from Microsoft) that lets a developer (well, anyone who gets the plug-in, actually) to view the message traffic that goes on behind the scenes from the browser to the server? I saw this one in action but I forget its name. And I think, for the FireFox broswer, you can simply turn it on somehow without getting a plug in.
It cuts the browser window in half horizonally and the bottom half is also divided vertically and you can see the GET and POST messages as well as the complete header information that is sent to the server from the browser across the internet.
HttpWatch is a great plugin for IE, but it's not free. Microsoft also released a free tool called VRTA which works for all browsers, but isn't a plugin.
For firefox it's called Live HTTP Headers. Another option of course is WireShark.
Fiddler is from Microsoft.

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.
I am working on a web application that needs silent printing (without print dialog box) with client side printer.
After some research we found that we can make it work using ActiveX and Foxit Reader.
Currently it works great but it constraints us with IE only and we want to make it work with Firefox and Chrome as well.
I know there is no direct code to make it work, but there must a work around?
What I need is the point to start e.g. Chrome/Firefox plugins to access local printer - or make windows service that runs in background in the client side, change browser settings, use ActionScript etc.
It will also be great if someone also illustrate how Facebook access local webcam from its website it may make about accessing clients peripherals from website. Thanks in advance.
For anyone who still wants information regarding printing on Chrome and/or FireFox without the use of ActiveX, extensions or client-side scripting, please see my answer to another question similar to this.
We have an application that is built exclusively in dev mode using the embedded jetty server that comes with GWT. We also host on jetty.
There are a number of pages we use for development only to do things like simulate SSO requests, view emails that were sent through the system, and check what files are uploaded.
When we try to link from these pages into a GWT page the problem becomes that &gwt.codesvr=192.168.0.101:9997 is not included in the URL and we get the error message "GWT module 'YourApp' may need to be (re)compiled". Obviously I can paste in "&gwt.codesvr=192.168.0.101:9997" manually but is very annoying. Does anybody know of a way to detect you are in the embedded Jetty dev mode server and auto generate links to have the correct "&gwt.codesvr=192.168.0.101:9997" added on?

I've updated this bookmarklet. It isn't perfect, but makes it quick while developing.
I suggest you create a Filter which will simply redirect you to an address with &gwt.codesvr=192.168.0.101:9997 as soon as you navigate to the one of the "development pages". If codesvr parameter is specific for each developer, each developer will have to set it in some cookie and filter will simply take this value from cookie.
I would like to test a webpage in multiple browsers, in my local machine. I see that most of the online services provide screenshots, but I cant really see what happens when i click a link on the webpage.
Are there any software where i can see how the webpage is actually functioning on user events like click etc.?
The only tool I known is Selenium
hope it helps!
