Many readers of my post on booking tatkal tickets with Firefox's autofill forms extension have reported that IRCTC has now disabled right clicks. Not only does this hamper saving the form, it is also very annoying. I've found a workaround for this. After you fill in the form do not directly go and right click to save the form as a profile. Instead paste this code into the Firefox address bar -
javascript:void(document.oncontextmenu=null) .
This will re-enable the disabled right click. Now proceed as before.
This code can be used on any site that disables right click
