Hello, Please note that, starting from Firefox 31.0 (now in the testing repository) Sabayon will provide separate packages for language packs (www-client/firefox-l10n-*). So don't be surprised if Firefox doesn't speak your language after update. :) 82 packages are available for this version!
Previously, Firefox packages have been providing only a fraction (a half or so) of the languages supported by the browser.
