Mozilla Foundation has worked to correct the 2 security vulnerabilities discovered in these days, and has release new versions of its products: Mozilla Suite (1.7.2), Mozilla Firefox (0.9.3) and Mozilla Thunderbird (0.7.3) are now available to download.
Only an alert... normally the Mozilla installations can easily overwrite the previous versions installed without problems, but I recommend to save all your plugins before upgrading (contacts and bookmarks are in a user default settings folder and you don't loose them).
The Web Version of MSN Messenger is ready to go... 
This is a great idea and a great feature for MSN Messenger... if you're out and you can't install MSN on your PC, you can keep in touch with your friends simply by going to the MSN Web Messenger Site and login on it.
Only a little alert about it... it requires that you turn off your Popup Blocker, and it's really noise. Windows XP Service Pack 2 doesn't have a Popub Blocker turned on by default? I think there could be some little problems... 
MSN world is in a continuous big improvement phase... Blogging services, Search capabilities (on the web and also on the desktop) are only an example of this. Good!
