Within JSP files, I have some pretty complicated Javascript. On a production machine, we're seeing a very weird bug that we have not been able to understand. We have never been able to replicate it in a local or development environment. It might be related to the javascript, but I haven't found a good way to do this: use my browser to visit the page (on the production website) and then use browser tools to edit the javascript that runs on that page, including on reloads of the page. I'm always able to do this to tweak CSS etc, but as these questions point out, it's not obvious how to tweak JS

Recently, I came across an issue where a CGI application is not responding. Symptom is Firefox displaying: Transferring data from localhost... But the thing is I cannot see any traffic from Firebug's Net panel, and the browser just stays on the same stage forever. I am thinking about the ways to debug this application but I cannot see the source code or any of its compiled Java/C++ components, therefore I reckon a HTTP network level of diagnostics is a good start. I have little experience in Fiddler and Wireshark, just wondering will they get better feedback/statistics in the HTTP network

I want to write a browser (Chrome/FF) extension that needs to select an element on a web page. I would like it to behave like Firebug's element inspector does. You click the inspect arrow and you can then hover/highlight elements. When you click on the element you want, the element is inspected. I'm just interested in the code to allow a user to select an element - not in actually inspecting it or anything similar. Because I'm writing an extension, it might be nice if you could provide non-jQuery/Prototype/etc.. code so I don't have to distribute that. I wrote an implementation of this using

I am using Firebug 1.10.2 with Firefox 14.0.1. When showing a web page, the Firebug add-on has this "behavior": Firebug’s “Aborted” message upon Ajax request . What should I make? Is it so dangerous that I must improve my web application because the presence of some error, or it is a Firebug bug or something else? Please see the documentation of XHR open() for example here: https://developer.mozilla.org/en-US/docs/DOM/XMLHttpRequest Note: Calling this method an already active request (one for which open()or openRequest()has already been called) is the equivalent of calling abort(). Just create

As mentioned in a previous question, I'm coding a crawler for the QuakeLive website. I've been using WWW::Mechanize to get the web content and this worked fine for all the pages except the one with matches. The problem is that I need to get all these kind of IDs: <div id="ffa_c14065c8-d433-11df-a920-001a6433f796_50498929" class="areaMapC"> These are used to build specific matches URLs, but I simply can't. I managed to see those IDs only via FireBug and no page downloader, parser, getter I tried was able to help here. All I can get is a simpler version of the page which code is the one you can
