Update : IRCTC has blocked Quick book from 8 AM - 9 AM. This method will not be useful in such a scenario.
This article is a short demo to using Firefox's Autofill Forms extension to book tatkal tickets. First step is to go to https://addons.mozilla.org/en-US/firefox/addon/4775 and install the extension. You'll need to restart Firefox for the extension to take effect.
Now that it's done, head to the IRCTC
website and login. Now head to the Quick Book page. You can fill in the
details.
If you do not know the train number, you can get it from the "Plan My
Travel" page. Now that you've filled up all the details you want to,
right click on one of the form textboxes.
Edit : IRCTC has now disabled right clicks. As a workaround you need to paste javascript:void(document.oncontextmenu=null)into your address bar to re-enable the right click. See my post on IRCTC's disabled right click.
Click on the "Add complete form as profile" option.
A new window like this will now open up
You can close the window and reload the QuickBook page. Press the Alt+j key combination to autofill the form. You can reload the page as many times as you want and press Alt+j to autofill.
This post is dedicated to my good friend Dhanya.
Edit : OK, I'm giving into blackmail from someone crafty and cunning(not my words) :P
@gjoos : i want my name included in that blogpost if you want me to TRY booking tickets for you tomorrow !!! :P
