I am debugging one script quitely hard to understand and need to track all the post and get requests, occured while visiting page in Google Chrome. Which plugin should I use?
Found it. Deleloper Tools - Network tab has done the job!

There is a Facebook app which has enabled the depricated facebook-chat feature where users can chat whilst playing their game. Unfortunately there has been a dirge of spammers and scammers posting in this chatroom, which we would wish to automatically detect and send emails or some other alerts to us so that we can more immediately block/ban these users.
Is this possible somehow? What we've tried was to create a python scraping application but it wasn't immediately obvious how to log into facebook and get HTML of an app through a python call.
I've since been introduced to bookmarklets as a concept. Perhaps this could solve the issue? There could be some type of javascript code in a bookmarklet, and all one would need to do is load up the game, open the facebook-chat, and then click the bookmarklet, and leave the computer running 24-7. The javascript would parse the DOM for suspected scam links and send email reminders when found.
This is just me brainstorming possible ideas. I'm really not sure how to approach this automation problem, and I am not finding anything useful online either.
It seems that the latest update of Google Chrome 44 to 45 is blocking clickonce applications.
Our clickonce application is working fine and is in production for over weeks.
This morning we got reports that when users tried to download our application it straight end up in the Downloads tab with following message: "[...].application may harm your browsing experience, so Chrome has blocked it. Recover malicious file". After clicking that message a confirmation dialog is shown and if that gets accepted the user can download the application file.
Is anyone else having the same experience with their clickonce applications and do you have any idea how to get around with it?
Thanks for any ideas / help!

It looks like it might have just been raised in the Chromium issue tracker:
https://code.google.com/p/chromium/issues/detail?id=532952
Quoting from there:
My understanding is that if Google has not scanned the file because it is unreachable or isn't aware of it (no public links so it can't be crawled), Chrome will block the application."
In latest version things are worse: There is only Suppress button next to the message "xxx may harm your browsing experience, so Chrome has blocked it" with no links for "recover". The trick is to click on Show all downloads button on far right. There you will see the link for recovering the file that Chrome unnecessarily deemed as malicious.
I'm using an API on my website to send emails to the users and while testing my call I noticed I was receiving the email twice.
So the url looks like "localhost/api/sendEmail" and, at least on Chrome, when I'm on localhost and I start typing "/ap" the url is automatically completed.
And I can see on Fiddler that Chrome (well I think that's him) is actually calling it before I press Enter so the mail is sent, and when I press Enter it is of course sent a second time.
This is not a problem since it won't be directly callable by the end-user, but I was just wondering what is the purpose of this first call ? Is Chrome pre-calling the page to make it faster to load ? Can it cause problems in different situations? Can one prevent Chrome from behaving like this?
Again, not a problem at all, but I'm just wondering.
This is Google's prefetch feature, which loads the page quicker, assuming you execute the auto-completed URL.
You can disable this option in Google Chrome:
Settings > Advanced Settings > Privacy: (uncheck) Prefetch resources..
Update 2019
I came across a similar question on superuser, which I provided an updated answer for.
Disable page load prediction service
chrome://settings/ -> expand Advanced section
Disable NoState Prefetch
chrome://flags -> search for "nostate"
I'd like to try my hand at some Chrome Extension Development. The most I have done with extensions is writing some small Greasemonkey scripts in the past.
I would like to use localStorage to store some data and then reveal the data on a extension button click later on. (Its seems like this would be done with a popup page)
How do I run a script everytime a page from lets say http://www.facebook.com/* is loaded?
How do I get access to the page? I think based off my localStorage requirement I would have to go down the background_page route (correct?) Can the background page and popup page communicate across the localStorage?
UPDATE:
I'm actually looking to learn the "Chrome way". I'm not really looking to run an existing Greasemonkey script
Google actually has some pretty good documentation on creating extensions. I recommend thoroughly reading the following two articles if you haven't already done so:
http://code.google.com/chrome/extensions/getstarted.html
http://code.google.com/chrome/extensions/overview.html
If you want to give your extension access when the user browses to Facebook, you'll need to declare that in the extension's manifest.
Unless you're wanting to save data beyond the life of the browser process, you probably don't need to use local storage. In-memory data can just be stored as part of the background page.
Content scripts (which run when you load a page) and background pages (which exist for the duration of the browser process) can communicate via message passing, which is described here:
http://code.google.com/chrome/extensions/messaging.html
Overall, I'd suggest spending some time browsing the Developer's Guide and becoming familiar with the concepts and examples.
Chrome has a feature to automatically convert greasemonkey scripts to extensions!
I am on a mission to expand my knowledge and create an extension for chrome similar to how firephp works. I want to integrate with my existing logging and debugging api within my framework and I want to be able to send these messages to the console. Nothing really robust to start with just a way to send debug messages to the chrome console from php.
The plan is to send the messages via the headers and have the extension read those headers and interpret them. I've been trying to find information on accessing the response headers and can't find any examples. Some of the research has led me to possibly having to develop an NPAPI plugin to be able to accomplish this.
Before traveling down a dead end path I wanted to get the communities opinion here on which path I should be taking to find a solution.
Chrome cannot currently do this, but Google is working on it. A preliminary and incomplete implementation is in the development version of Chrome, or in Chrome Canary.

The web request api is now in stable and can be used to access header events.

Here is an extension that does what you are trying to do. It uses cookies to communicate, from what I can tell.
