Thanks for filing this bug.

The TabManager is currently only implemented on Desktop, so we'll either have to remove the dependency on it from webRequest or add support for it on Android.

Bug 1260548 is the tracking bug to add support for the Tabs API on Android (which will include the implementation of the TabManager).

Taking a quick peek at ext-webRequest.js I notice that TabManager is only used once, to get a tabId, and that tabId is only used to check that the tab exists at all (not -1). Seems to me that a quick fix might be to simply not do that, and remove the reference to TabManager...

leave out tabID on android
