Mozilla released Firefox 1.0.5 on 07/12/05 and Thunderbird 1.0.5 on 07/13/05. Mozilla made many security fixes and stablilty impovements for both programs. These fixes will make both programs safer. The most critical fixes had to do with javascript spoofing. This has lead to people visiting homebanking and other similar sites that actually look exactly allike and even show the correct URL, but is not real. I think everyone should update to the latest version as soon as possible. In the future Mozilla updates will be much easier becuase it won’t be required to download the entire program each time you update. They will start to launch “patches”instead of full installs after v1.1 is released.
