...without this notification, the plug-in cannot tell whether a request with a null target failed or a request with a non-null target was completed.

Static method - MDN Web Docs Glossary: Definitions of Web-related terms
examples in the notifications api, the notification.requestpermission() method is called on the actual notification constructor itself — it is a static method: let promise = notification.requestpermission(); the notification.close() method on the other hand, is an instance method — it is called on an specific notification object instance to close the system notification it represents: let mynotification = new notifica...

Introduction to web APIs - Learn web development
examples include telling the user that a useful update is available on a web app via system notifications (see the notifications api) or vibration hardware (see the vibration api).
...as an example, the notifications api asks for permission using a pop-up dialogue box: the web audio and htmlmediaelement apis are subject to a security mechanism called autoplay policy — this basically means that you can't automatically play audio when a page loads — you've got to allow your users to initiate audio play through a control like a button.

JavaScript object basics - Learn web development
as an example, the notifications api — which allows modern browsers to fire system notifications — requires you to instantiate a new object instance using the constructor for each notification you want to fire.
... try entering the following into your javascript console: const mynotification = new notification('hello!'); again, we'll look at constructors in a later article.

Deploying our app - Learn web development
and even better, whenever we make a change and push the change to our remote git repository (on github), this will trigger a notification to netlify which will then run our specified build task and then deploy the resulting dist directory to our published site.
... could you set up a notification to let you know when a new deploy succeeded or failed?

Process scripts
similarly, some observer notifications must be registered in the content process, but if you do this in a frame script, and the frame script is loaded more than once, then you will get multiple notifications for that event.

Implementing Download Resuming
(it is possible to pass an empty string as the id; however, this means that you have no assurance that the file remained unchanged) now, you can open the channel as usual (using nsichannel.asyncopen() in the common case) and write to the file in the ondataavailable notifications.
... you may want to use nsisimplestreamlistener to simplify this task; to get progress notifications, you can implement nsiprogresseventsink and set an interface requester as the notificationcallbacks of the channel that gives out such an event sink (this needs to be done before calling asyncopen).

About NSPR
this mechanism provides the basic mutual exclusion (mutex) and thread notification facilities (condition variables) implemented by nspr.
...the java-like facilities include monitor reentrancy, implicit and tightly bound notification capabilities with the ability to associate the synchronization objects dynamically.

Condition Variables
this chapter describes the api for creating and destroying condition variables, notifying condition variables of changes in monitored data, and making a thread wait on such notification.
... a call to pr_waitcondvar causes a thread to block until a specified condition variable receives notification of a change of state in its associated monitored data.

PR_NotifyCondVar
notification of a condition variable signals a change of state in some monitored data.
... when the notification occurs, the runtime promotes a thread that is waiting on the condition variable to a ready state.

Mailbox
this may seem like a lot of infrastructure just to read messages from a flat file, but it allows us to do it asynchronously, and to have reading local messages fit into the same kind of mechanisms that reading nntp and imap messages do - running urls, getting onstart/stoprunningurl notifications when the url starts/stops, etc.

Filter Incoming Mail
by example, setting it to lower case subject = subject.tolocalelowercase(); // then we rebuild a subject objet by rencoding the string // and assign it to the message headers and we're done amsghdr.subject = mimeconvert.encodemimepartiistr_utf8(subject, false, "utf-8", 0, 72); } } }; function init() { var notificationservice = components.classes["@mozilla.org/messenger/msgnotificationservice;1"] .getservice(components.interfaces.nsimsgfoldernotificationservice); notificationservice.addlistener(newmaillistener, notificationservice.msgadded); } addeventlistener("load", init, true); have a look to nsimsgdbhdr to get the full list of properties to be modified.
