Start the <b>beta</b> version of Thunderbird (with release version not running) and it will use the <b>default-beta</b> profile. On first use Thunderbird will create the <b>default-beta</b> profile, and it will prompt you to define your accounts. If you need to bring some data from your release profile into the beta profile, consult the <a href="https://support.mozilla.org/kb/thunderbird-beta">beta support article.</a>
Pokrenuti <b>beta</b> inačicu Thunderbirda (kada stabilna nije pokrenuta) i koristiti će <b>zadani-beta</b> profil. Priliom prvog pokretanja Thunderbird će stvoriti <b>zadani-beta</b> profil i zatražiti će vas da definirate svoje račune. Ukoliko trebate prebaciti neke podatke iz stabilnog profila u beta profil, posjetite <a href="https://support.mozilla.org/kb/thunderbird-beta">članak beta podrške</a>.
