Question

我正在通过ActiveDirectory域部署适用于Chrome的WebExtension。此域中的计算机无法连接到Internet。只有Intranet中托管的网站可用。因此，我使用ExtensionInstallForcelist策略在Chrome中安装WebExtension（不将其上传到Chrome网上应用店）。在Intranet中，存在一个服务器，它托管WebExtension（.crx文件）和更新清单XML文件（指向.crx文件）。

Chrome版本62.0.3202.94一切正常。应用该策略后，WebExtension将安装在Chrome中。 WebExtension是强制安装的，因此用户无需手动激活它。

但是自从Chrome版本63.0.3239.84出现问题。 WebExtension已安装，但已立即停用。此外，我观察到一种奇怪的行为。启动Chrome后，WebExtension会在短时间内激活，但之后会立即停用。这种情况会发生几次，直到行为消退为止。如果Chrome已关闭并重新启动，则会重复此行为。在多个设备和其他域中的计算机上会出现此问题。

我检查了网址chrome：// policy。 ExtensionInstallForcelist条目已正确应用。

在chrome_debug.log中，Chrome似乎尝试在某个网址上检查WebExtension，但检查失败。问题也出现在＆＃34;版本63.0.3239.108＆＃34;和版本64.0.3282.24（官方版）beta（64位）＆＃34;。在同一台机器上使用62.0.3202.94版本，一切正常。

为了更好地概述，我将在chrome_debug.log
