[Tracking Requested - why for this release]: We'd like to ship this change in 84 to meet the timeline for a planned experiment. The change will be narrowly scoped to only affect Urlbar extensions, which can currently only be used by Mozilla in experiments. No other Urlbar experiments are running in 84. UrlbarProviderExtension.notificationTimeout [controls](https://searchfox.org/mozilla-central/rev/168c45a7acc44e9904cfd4eebcb9eb080e05699c/browser/components/urlbar/UrlbarProviderExtension.jsm#287) how long extensions have to return a result before they timeout. The [default value is](https://searchfox.org/mozilla-central/rev/168c45a7acc44e9904cfd4eebcb9eb080e05699c/browser/components/urlbar/UrlbarProviderExtension.jsm#393) 200ms. This may not be enough time to get a response from some web services that we want to experiment with in the Urlbar. We should change notificationTimeout into a hidden pref that Urlbar experimental add-ons can set via experimental APIs.
