Bug Description

Currently, every access of navigator.userAgent results in a synchronous IPC request to the browser process where we call in to the WebContextDelegateWorker for the particular context if there is one, in order to lookup an override for the user agent string. This should really be cached on the renderer side so that we only do one call until the document URL changes

Chris Coulson (chrisccoulson) wrote :

This will sort-of be fixed by the implementation of bug 1410753, in that the data supplied to WebContext.userAgentOverrides will be serialized and shared with content processes. As the new WebContext.userAgentOverrides API will effectively deprecate the existing mechanism to override navigator.userAgent, it's not worth spending additional time fixing this specifically for the old mechanism.
