You will find in bug #569851 instructions about the page to be localized for the Major Update box proposed to our Firefox 3.0 and 3.5 users to update to 3.6. The file is on the SVN repository in your locale folder, preferably commit directly to SVN and once done, inform in this bug. Alternatively, you can attach the translated file to this bug. If you attach an .html file, please attach it with the plain/text Mime format. News and instructions affecting all locales will be posted and updated if necessary in the master bug. Thanks!!
