Mozilla has patched the Firefox browser and Thunderbird email client with a series of security updates.
Firefox was fixed up with 11 security patches, nine of which were critical. The other two were rated high and moderate.

Mozilla fixed 68 other bugs in Firefox to boost the browser's stability. The browser is now at version 3.6.13, and awaiting the delayed arrival of Firefox 4, which had been expected to arrive this year, but now won't hit be available until early 2011.
Mozilla also updated Thunderbird to versions 3.1.7 and 3.0.11, fixing problems with large email folders and boosting performance, stability and security.
"Thunderbird 3.0.11 is the last security and stability update for Thunderbird 3.0.x," Mozilla warned. "Thunderbird 3.0.x users will be prompted and encouraged to start using Thunderbird 3.1 starting early next year."
