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. 
附加组件作者没有义务让附加组件能够在测试版中正常运行。因此在测试版中，您的所有附加组件都可能无法运行，即使其目前能运行，也无法保证以后依然可以。如需帮助，请参阅<a href="https://support.mozilla.org/kb/thunderbird-add-ons-frequently-asked-questions#w_what-if-my-add-on-is-broken">附加组件常见问题解答</a>。
