Привет мир приложение не работает в Firefox 7.0.1

Question

Я не могу открыть приложение Hello world в Firefox 7.0.1. Я разрабатываю это приложение, используя это руководство из документации Sencha. Когда я открыл Firefox Web Developer Console, я обнаружил следующие ошибки CSS:

Я хотел бы знать, почему появляются эти многочисленные ошибки и как их устранить?

Answer 1

Я просто сделал то же самое в той же версии Firefox (и в версии 8.01), и я получаю те же предупреждения (а не ошибки), что и вы.

Видимо, это старая проблема: http://www.sencha.com/forum/showthread.php?10956-Solved-css-warnings-feedviewer-in-firefox-2
