I looked into this error in some detail. The service URLQueryStrippingListService
is being initialised by the profile-after-change
event. The event is being passed to the observe()
method, which doesn't recognise the event and so triggers the error.
This seems odd: why be initialised by an event that's going to cause an error? There is some discussion in the bug report and changesets about the fact that the profile-after-change
event isn't triggered for content processes in fission, so maybe this is why?
In other situations where gecko is used there are reports of this error appearing, for example on macOS and Thunderbird. However I don't see any changes to address this in the latest gecko version.
The error doesn't itself seem to cause any problems, just messy log output.
Given all this it looks like it must be a case of one of the following:
My feeling is that it's probably a case of 1 or 2 and so have added code to suppress the error, see the following commit: https://github.com/llewelld/gecko-dev-mirror/commit/1fe7c56c7363d093b5eadec73d872340467970b4
