Add-on authors are not obligated to make their add-ons work in beta. Some or all of your add-ons may not work. Or if they do work today, they may not work tomorrow. Consult the <a href="https://support.mozilla.org/kb/thunderbird-add-ons-frequently-asked-questions#w_what-if-my-add-on-is-broken">Add-ons FAQ</a> if you have difficulty. 
Autori dodataka nisu obavezni uskladiti svoje dodatke s betom. Neki ili svi dodaci možda neće raditi, ili ako rade sada, možda neće raditi kasnije. Posjetite <a href="https://support.mozilla.org/kb/thunderbird-add-ons-frequently-asked-questions#w_what-if-my-add-on-is-broken">ČPP o dodacima</a> ukoliko imate problema.
