All extensions which can be directly downloaded are downloaded now. The progress is shown in the Download and Installation dialogue box. If an extension cannot be downloaded, a message is displayed. The operation continues for the remaining extensions. Some extensions may be marked with the phrase &quot; browser based update &quot; . These extensions cannot be downloaded by the Extension Manager. A web browser must be opened to download the extension update from a particular web site. That site may require several more user interaction to download the extension.
现在将下载所有可直接下载的扩展。“下载和安装”对话框将显示进度。如果无法下载某个扩展，将显示一条消息。此操作将继续进行，以下载其余扩展。
