The usual recommendations for a web development and debugging web browser are Firefox/Firebug or Safari/Web Inspector.
But I like Google Chrome, and would like to use this as my primary development browser. What plugins or tools should I get to optimise my web programming experience with Chrome?
Google Chrome's own "Firebug" is very good, just right click and inspect element to bring it up.
Frame two pages is helpful.
Chris Pederick's Web Developer toolbar is good too.
The Development and Coding Search (Chrome extension) is one of many Chrome extensions for developers. See the featured web development extensions for more developer-friendly extensions.
Pendule has a lot of good bits and bobs under one extension/icon. Few things I like about it...
View generated source
Colour picker
Ruler
Validator
There are probably tons of alternatives, but it's the best I've seen so far.

Really Quick question:
Why does the Brave browser have Chrome's dev-tools?
Does this also mean that I don't need to test my website in Brave if it works in Chrome?
Thanks :)
Take a look at their github page. Especially the tags they added:
Notice the word "Electron", now I could explain to you what Electron is but they have an excellent explanation on their Electron Home page:
Electron is an open source library developed by GitHub for building
cross-platform desktop applications with HTML, CSS, and JavaScript.
Electron accomplishes this by combining Chromium and Node.js into a
single runtime and apps can be packaged for Mac, Windows, and Linux.
As you can see, Electron uses "Chromium". I could explain but.... you've guessed it they offer a great explanation themselves:
The Chromium projects include Chromium and Chromium OS, the
open-source projects behind the Google Chrome browser and Google
Chrome OS, respectively. This site houses the documentation and code
related to the Chromium projects and is intended for developers
interested in learning about and contributing to the open-source
projects.
So thats why you can access the chrome dev tools inside Brave.
On to your other question:
I don't need to test in Brave if my website works in Chrome?
Yes and no, you can be fairly certain that Brave will do everything Chromium does. But in the end we can't be certain what Brave does to the pages loaded through it. Having said that I won't be giving you a firm answer on this :)
(PS: if you set up automatic testing it doesn't really matter if you have to test another browser)
Early on I was doing some debugging and testing using the chrome dev tools(known as inspect element). I found out that on the Resources column of the dev tool, Chrome can always access the resources from the server and display them(links, videos, images....). Just wonder how Chrome does that. Is there any way to write a piece of code doing the same thing(access the server resources of other websites, not modifying them but displaying, stuff like, the link of the video currently playing on the website, which usually does not pop up until the play button is hit)?
DevTools doesn't fetch resources from a site. It fetches them from the browser.

How does webkit/chrome's WebInspector Resources Inspection work?
and
Getting Information from Google Chrome's Developer Tools
The Chrome Developer Tools has two parts frontend (html+javascript) and backend (C++) and there is an API which specifies the protocol between these parts. You can see the specification here. You can use it for writing your own app instead of standard DevTools frontend.
Also there is experimental debugging API for chrome extensions.
I think the Webkit WebInspector go over the hole source code and match all resources of the source.
So it match <link href="something.css"> and then it place something.css in the resource panel under stylesheets. And exactly the same thing for the other tags.
It's not hard to make regexes for this.
Any specific tools are there to develop the application using html 5?
I had used Aptana studio, I feel it is not fully user friendly tool to write a html 5 application.
http://marakana.com/bookshelf/html5_tutorial/index.html take a look at that for starter points.
This is a great, easy to read tutorial which will almost definitely help you learn HTML5 and CSS - http://net.tutsplus.com/articles/news/30-days-to-learn-html-and-css-a-free-tuts-premium-course/
For debugging, you can use Chromes developer tools (F12 on the keyboard) or the same on Opera & Internet Explorer. For Firefox download "Firebug".
Another "debugging" tool is http://html5.validator.nu/ which will validate your HTML and show any errors.
Notepad++ is a great free app to start developing HTML5 on, you can also use others, for example Aptana is a great IDE. For one with a GUI, I'd advise purchasing Dreamweaver, it is expensive but I say it's the best for learners.
I'd like to analyze the structure of some complex web pages that I've visited. Manually parsing out tags in the HTML source is tedious and prone to errors.
I'd like to find a utility that will accept HTML source (or a URL) as input, and show the hierarchical arrangement of the HTML elements, including source and id attributes, preferably in a treeview.
I was confident that it should be easy to find such a tool, but a few Google searches haven't turned up anything for me. I'm still confident that such a tool exists. Can the community help me find something? (I'm a Windows user and of course would prefer free if possible.)
IE8+ and Chrome both have wonderful developer tools built right in. Just visit a webpage and in IE, press F12, and in Chrome, go to wrench->tools->developer tools. They both show the tree view of the page as well as let you modify it. They're both very powerful.
Most browsers have a DOM viewer built in. Firefox has a third party extension that provides this.
These will all show the DOM after error recovery has been performed by the browser, before then you can't be sure that a valid tree could be constructed.
You can also use any good editor like Notepad++ which has highlighted syntax and node collapsing.
As other have mentioned, most modern web browsers have "developer tools" built into them which include a way to browse the HTML source in a tree-view. I've put together a quick screenshot comparison of the tools that the latest versions of the top five browsers (Internet Explorer 9, Firefox 4, Chrome 12, Opera 11 and Safari 5) offer.

Use firebug or DOMinspector addon on firefox.
Download Firefox (http://www.mozilla.org/) and install the
Firebug addon https://addons.mozilla.org/firefox/addon/firebug/) BOTH ARE FREE
For the last few years I have been using Firefox, Firebug, and the Web Devevloper Firefox toolbar for all my web dev needs, quite happily. I am, however, very interested in experimenting with moving my web dev support over to Chrome, but I have no idea where or how to start. How much functionality is build into Chrome and how do I access it? What add-ins do I need and where do I learn about using them?
These are two of many questions I think face most web devs moving into a much less familiar environment. I'm trying to ask a broader question here, along the lines of, what do I need to use and know for effective web deb and JavaScript debugging in Chrome and where is best to learn what I need to?
Google Chrome (as well as Safari) has really underestimated Developer Tools feature. Lots of developers are indifferent to it and use Firebug through habit. (to no purpose!)
But for me it is the main debug tool: it looks more pleasant than the latter and includes a way cooler features. (e.g. Timeline — separate time intervals for Loading, Scripting and Rendering).

→ From google webmasters-faq:
There are several tools to help you test your website in Google Chrome:
Web Inspector
Right-click on any component on a web page to launch the web inspector. You'll be able to see the elements and resources associated with the component on which you clicked, including a hierarchy view of the DOM and a JavaScript console.
Task Manager
Select the Page menu icon, then Developer > Task Manager (or press Shift+Esc). The task manager shows all running Google Chrome processes, and the resources that they're using (memory, CPU, and network).
JavaScript Debugger
Select the Page menu icon, then Developer > Debug JavaScript. This launches a JavaScript debugger that can be used to attach to existing processes.
in chrome: right click and "Inspect Element"
the Light Version of Firebug is available too.
While in Chrome, press Ctrl+Shift+I and start experimenting. It's all you'll need.
The Web Developer port from Firefox is very handy.
