reject-importGlobalProperties
Rejects calls to Cu.importGlobalProperties
or
XPCOMUtils.defineLazyGlobalGetters
.
In system modules all the required properties should already be available. In non-module code or non-system modules, webidl defined interfaces should already be available and hence do not need importing.
For sjs test files, if the relevant global is not already available, then consider extending the list of globals available from the httpd server.
Options
“everything”: Disallows using the import/getters completely.
“allownonwebidl”: Disallows using the import functions for webidl symbols. Allows other symbols.
