UAQ: UnAnswered Questions
Question: How can we programmatically extract the subject, sender, date and the body of an e- mail when you are reading one (in Thunderbird presumably)?
Could someone make an adressbook enchancer extension.
Question: Could someone make an addressbook enhancer extension that has the ability to put pictures on a contact and other features the Thunderbird address book lacks.
Answer. None. The question is not specific enough, is too open ended and ambiguous.
Saving a whole news thread Saving a whole news thread
Question: Is there a way to save a whole news thread in Thunderbird?
Answer: None this week.
Question: We're seeing a timing issue when using nsITimer on MSWindows that does not occur on GNU/Linux.
A javascript XPCOM component sets a TYPE_ONE_SHOT timer to go off in one hour. The timer does not go off until significantly (more than 2X) after that. Anyone else seems different nsITimer behavior on Windows or have any sort of explanation about whether this is a problem with the win32 timer implementation, or whether there is some workaround?
Answer: No answer this week.
FAQ: Frequently Asked Questions
Plugin or Extension? Need to launch Windows Explorer instance from a URL
Question: In IE, when I enter a URL that starts with "file://" in the address bar, an instance of the windows explorer will be launched and display the directory in the URL. However, in Firefox, a custom directory listing will be displayed instead of Windows Explorer. Is there anyway, via plugin or extension, for Firefox to mimic the functionality of IE in this respect?
Answer: The IETab (Opens IE in a Firefox tab) should be able do this if you set it to always open "file://*" URLs in an IE tab.
The appearance with a FireFox tab isn't quite the same as having a completely separate Explorer window. However, it's functional and does allow for the Explorer to be handling the display of the folder contents, and all of the right-click context menu support is present so it should meet my needs.
packaging to release on Mozilla extensions site
Question: Hi, I am planning to release our extension on the mozilla extensions site. When I tried uploading it, it said that update.rdf contains invalid location. What is the valid one and what other things do I need to change to make it work on Mozilla site?
Answer: You must remove updateURL from the install.rdf and use a known to AMO minVersion/maxVersion. It's mentioned in their FAQ I believe. No confirmation that the answer given worked yet.
Question: The Function "LoadURL" loads a URL in the Browser window:
function LoadURL(URL)
{
window._content.document.location = URL;
window.content.focus();
}
Is it possible to open the URL in a new tab?
Answer:
var tab = getBrowser().addTab( url );
// And if you want it to load in foreground: getBrowser().selectedTab = tab;
Is it possible to read the html-code of the current URL/site?
Question: Is it possible to read the html-code of the current URL/site?
Answer: Yes, this is possible. Use the DOM API (http://www.w3schools.com/dom/default.asp has a good tutorial).
Not the best answer but a good starting point for the question asker to do some research towards the answer.

Any Data Encryption Libraries?
Question:
Are there any built in libraries that can be used to encrypt data?
Answer: Yes.
1. You can use nsISecretDecoderRing.encryptString() and nsISecretDecoderRing.decryptString(). However, I'm not sure how/if that works if the user hasn't defined a master password in Options->Security->Use a master password.
2. You can AES-128 or AES-256 symmetric encryption via aes.js (http://tinyurl.com/pp79t).
No confirmation from the question asker on whether this answer was helpful in solving their problem.
