Firefox 3.6 will warn users if one of their plug-ins, such as Adobe Flash Player or Windows Media Player, is outdated, Mozilla said. Having an outdated plug-in could expose users to security vulnerabilities.
Users will see the warning if they visit a web page that uses the out-of-date plug-in. The warning will take users to a site where they can download the latest version of each outdated plug-in.
Older versions of Firefox (3.5.3 and 3.0.14) warn users if their Flash Player plug-in is not up to date, but this feature has been expanded in version 3.6 to warn users if any plug-in is vulnerable, Mozilla said.
The new version does not contain any security fixes.
