Release Date: February 23, 2007

Following security bugs have been fixed in this release;

• Embedded nulls in location.hostname confuse same-domain checks
• Mozilla Network Security Services (NSS) SSLv2 buffer overflow
• XSS and local file access by opening blocked popups
• Spoofing using custom cursor and CSS3 hotspot
• Information disclosure through cache collisions
• Improvements to help protect against Cross-Site Scripting attacks
• Crashes with evidence of memory corruption (rv:1.8.0.10/1.8.1.2)

Windows vista is supported with some shortcummings;

• For Vista, it is recommended that Firefox be installed in the default location. If the browser is installed in a non-default location, software updates may fail. You can reinstall the software to the default location or to a non-default location as long as the install folder is named “Mozilla Firefox”. Alternatively, you can start Firefox by right-clicking on its icon and selecting “Run as administrator” from the menu.
• A Windows Media Player (WMP) plugin is not provided with Windows Vista. As a workaround, in order to view Windows Media content, you can install the WMP Plugin v6.4 for Netscape Navigator.
• Vista Parental Controls are not completely honored. In particular, file downloads do not honor Vista’s parental control settings. This will be addressed in an upcoming Firefox release.
• When migrating from Internet Explorer 7 to Firefox, cookies and saved form history are not imported.

You can download Firefox in your language and for your operating system from this page.

For Firefox in english language and for windows operating system use this link.

If you are already using Firefox click Help on the menu bar and then select check for updates… and then install it from there. The reason why I am recommending it is that this way the install size is only 744 KB. While if you download the whole package it’ll be about 5.7 MB.
