Mozilla have just released Firefox 12 and Thunderbird 12. The new Firefox comes with easier updates. Now, the download manager will start your downloads as soon as you paste the URL.
For developers, support for CSS column-fill and text-align-last properties, support for ECMAScript 6 Map and Set objects have been added. The source view will now have line numbers making things easier for us.
Several days ago many big sites boasted that they found the link to this new Firefox. Many people have already downloaded that version. At that time, the change-log didn’t have any bug fixes or security fixes. But they have added some security fixes (2 critical, 3 high and 3 moderate) and two bug fixes (related to TinyMCE editors and OS X WebGL) in the last minute.
When it comes to Thunderbird, it have added message extracts for global search results. Support for add-ons that provide different types of local mail storage have also been added. It also carries several security and bug fixes.
So, because both of them fix bugs and security issues, its recommended to apply this update as soon as possible.
