Mozilla patched 10 Firefox vulnerabilities late Tuesday, seven of them marked "critical," but left a password-spilling bug unresolved.
Firefox 220.127.116.11, the first update since the October debut of Firefox 2.0, fixes 10 flaws while 18.104.22.168 patches nine. Both Firefox 1.5.x and 2.x will alert their users that an update is ready to install, but impatient users can download the fixes from the Mozilla Web site.
But a Firefox bug first reported Nov. 22 hasn't been fixed. The vulnerability, which Danish security tracker Secunia pegged as "less critical," could let attackers hijack passwords from Firefox sessions. Secunia has recommended that users disable the browser's automated password saving feature until a patch is produced. (In Firefox, users can select Tools|Options|Security, then clear the box marked "Remember passwords for sites.")
Mozilla on Tuesday also repeated earlier recommendations that users update to Firefox 2.0, as the 1.5.x line will be maintained with security fixes only until April 24, 2007. Firefox 1.x dropped off Mozilla's security support list in May.
Firefox 22.214.171.124 and 126.96.36.199 are available immediately for Windows, Linux, and Mac OS X.
