 HittingMaxWorkersPerDomain2=A Worker could not be started immediately because other documents in the same origin are already using the maximum number of workers. The Worker is now queued and will be started after some of the other workers have completed.
 # LOCALIZATION NOTE: Do not translate "setVelocity", "PannerNode", "AudioListener", "speedOfSound" and "dopplerFactor"
 PannerNodeDopplerWarning=Use of setVelocity on the PannerNode and AudioListener, and speedOfSound and dopplerFactor on the AudioListener are deprecated and those members will be removed. For more help https://developer.mozilla.org/en-US/docs/Web/API/AudioListener#Deprecated_features

-AppCacheWarning=The Application Cache API (AppCache) is deprecated and will be removed at a future date.  Please consider using ServiceWorker for offline support.
 # LOCALIZATION NOTE: Do not translate "Worker".
 EmptyWorkerSourceWarning=Attempting to create a Worker from an empty source. This is probably unintentional.
