Is it possible to open the client's web console in javascript (CTRL+SHIFT+K on Firefox)? Define the size, the position, else?
Thank you
I haven't heard of this being possible, and I couldn't find anything in a recent search about how to do it either. I did find another stackoverflow conversation about something similar here: Can I programmatically open the devtools from a Google Chrome extension?
From that, I surmise that if it's not possible from a browser extension, it seems even less likely to be possible from plain JavaScript.

I want to keep track from all the browser tabs I have opened. I searched it a bit and found out that I can achieve this with this command (for Chrome) chrome.tabs.query
So, do I need to build an extension for Chrome for this to work or I can achieve this with some Javascript code for example? (I think the first case)
Thanks in advance.
So, do I need to build an extension for Chrome for this to work
Yes. It would be a huge security problem if any website could monitor what happened in all other tabs open in the same browser.
or I can achieve this with some Javascript code for example?
Chrome Extensions are written in JS.
I'm looking for a way to record every thing I do in Chrome Devtools so I can play it back verbatim. I've seen a lot of docs on how to manipulate page content, track page performance and behavior etc from devtools extensions, but nothing yet about actually watching what I do in Chrome Devtools itself. I'd be willing to write an extension if that's what needed. The goal is a teaching tool where I can record things I'm doing in devtools and play them back. (Of course, one could use a GIF recorder but that's so 00's). Something I've looked a little bit at so far is chrome devtools protocol viewer but not sure if it could accomplish the task.
Can anybody suggest a potential way to accomplish this? Thanks in advance!
Now Chrome has an inbuilt recorder tool available in the Dev Tools. Much better than installing any 3rd party extension. Additionally, there are many more features to track the user journey.

You may try using Desktop Capture API which can be used to capture content of screen, individual windows or tabs. Here's a demo app that shows you how to use a Chrome extension to access the desktopCapture API in your web-application.

I would like to be able to know when arbitrary JavaScript successfully executes a command in a web browser. The medium doesn't matter, it could be a log, stack trace, event signal, it just has to be something that can be programmatically analyzed.
I've thought about this problem for some time now and I have not been able to come up with an adequate solution. I'm no expert with JavaScript though, so I'm wondering what ideas you have?
Since you'll probably be wondering why, it's just something I'm very interested in.
Any input is appreciated. Can you help me?
EDIT: I've investigated using something like Firebug to monitor JavaScript functions, however I wasn't able to determine if Firebug can be run programmatically on a simulated Web Browser (like a web-browser control in ASP.NET, which is what I'm currently using.) Does anyone know if it can?
You can use the profiler of Firebug.
Go to the console tab and click Profile. The profiler starts and all the javascript actions are "logged" till you click Profile again. Then you get the list of javascript functions that were executed in this interval.
A similar feature is available in most modern browsers' consoles.

The firefox browser could be used in asp .net using the selenium web driver and it also provide the ability to access all details from a web page. see the document and download api code and integrate it in your project its very easy to integrate using its help.

Does anyone know of any console emulator (preferably made in javascript or jquery) that would allow me direct access to the browsers javascript console that would be found in the developers tools in chrome for example? I have been using jq-console but that only emulates a terminal, very useful so far. However it only emulates a terminal and doesn't provide access to the browsers js console. I need this so that users have a front-end web based access to the console without having to open the developer tools or something similar, so they have access to the variables and objects available in the browsers js console. I had thought of loading the data into the memory of the jq-console instance however i think this would be a cumbersome process and i don't really know how to go about doing it without the information being directly entered into the jq-console instance. any help or guidance would be greatly appreciated. thanks in advance!
direct access to the browsers javascript console
No. Not without opening the console manually, and also you cannot do much more than logging messages. Any emulator will not use the native console.

Have you looked at their source code? You can write such one yourself, too. Or have a look at EloquentJavaScript's console script (using Mochi and Codemirror).
a browser console
…is not possible without only emulating it. However, you can use FirebugLite for that, which promises the same look-and-feel as the native Firebug. Also, Opera's Dragonfly is written in JS, and it is released as open source so you might adapt (parts of) it.
I'm attempting to find a bottleneck in my Javascript. Basically I'm developing a chrome extension written in Javascript which is taking 4-5 seconds to perform a task. There's a lot of code involved in the task and using print statements / chrome built in dev tools just isnt working. The dev tools don't seem to even see my Javascript running. I'm wondering if anyone has any advice / tools they think could be of benefit?
Open your page in Chrome.
Tools -> Developer tools -> Profiles
Start Profiling (3rd button, grey circle on the status bar at the bottom)
Perhaps it'd be a good idea to open the HTML files in Firefox instead of letting Chrome extensions handle it. That'd allow you to use Firebug to determine any causes, which would be very helpful.
I remember Google Chrome has a built-in JavaScript profiler. Or can't you use this for your extension? (I have never built Chrome extensions.)
You can try to use Profiler as it was mentioned before or Timeline.
Timeline will help you if the time was spent in native code.
