...you could just as well write the header expression like this: const header = <header> <h1>mozilla developer network</h1> </header> however, this looks kind of awkward, because the <header> tag that starts the expression is not indented to the same position as its corresponding closing tag.
...when compiled (using a tool like babel or parcel), our header expression would look like this: const header = react.createelement("header", null, react.createelement("h1", null, "mozilla developer network") ); it's possible to skip the compilation step and use react.createelement() to write your ui yourself.

Overview of events and handlers - Developer guides
event triggers include the completion of the loading of a resource on the network e.g., downloads an image that can now be drawn on the screen, the completion of parsing a resource by the browser e.g., processes the html content of a page, the interaction of a user with the contents of the page e.g., clicks a button.
...itting the event including: the window object, such as due to resizing the browser, the window.screen object, such as due to changes in device orientation, the document object, including the loading, modification, user interaction, and unloading of the page, the objects in the dom (document object model) tree including user interactions or modifications, the xmlhttprequest objects used for network requests, and the media objects such as audio and video, when the media stream players change state.

Necko Architecture
necko is a modular networking library developed as part of the mozilla project.
...necko provides the following libraries: necko - core networking functionality.

Necko FAQ
everything you wanted to know about the networking library in mozilla...
... a word rhyming with gecko and starting with the same letters as networking.

JSAPI User Guide
for example, a custom js object that provides direct service might be one that handles all of an application's network access, or might serve as an intermediary broker of database services.
...they do not provide access to files, the network, or anything browser-related.

Redis Tips
so rather than thinking about redis as a database with some kind of non-existent relationship to sql, think of it as a data structure server with a rich set of commands for querying and manipulating those data structures over a network connection.
... each redis command results in one network round trip.

The Publicity Stream API
possible error codes include: denied - if the user refuses to publicize the activity permissiondenied - if the publicizing site is not allowed to post to the publicity stream networkerror - if the publicity server is unreachable activityparseerror - if the activity contains syntax errors (not proper json) invalidactivity - if the activity contains semantic errors (i.e.
...possible error codes include: denied - if the user does not log in correctly permissiondenied - if the site is not allowed to access the publicity stream networkerror - if the publicity server is unreachable for_apps is a json list of apps that this store has (each represented as its origin url), so that stream events not relating to applications in a given presentation context can be excluded from the return value.

Component Internals
a set of default libraries stored in this components directory makes up a typical gecko installation, providing functionality that consists of networking, layout, composition, a cross-platform user interface, and others.
...for example, this is the object that may start a network download and implement interfaces that will listen to the progress.

Creating the Component Code
this is the object that contains the business logic, that implements functionality such as starting a network download, implementing interfaces that listen to the download progress, or providing a new content type handler.
...an nsifile object is usually a file or directory on a local volume, but it may represent something on a network volume as well.

Mozilla internal string guide
networking code prefers 8-bit strings.
... networking code tends to use 8-bit strings: either with utf-8 or latin1 (byte value is the unicode scalar value) semantics.

imgIDecoderObserver
load notifications are fired as the image is loaded from the network or filesystem.
... onstartcontainer() this load notification is called once enough data has been loaded from the network that we were able to parse the width and height from the image.

nsIApplicationCacheNamespace
constants constant value description namespace_bypass 1 items matching this namespace can be fetched from the network when loading from this cache.
... namespace_fallback 2 items matching this namespace can be fetched from the network when loading from this cache; however, if the load fails, the cache entry specified by the data attribute should be loaded intstead.

nsIBinaryOutputStream
this might be used, for example, to implement network protocols or to produce architecture-neutral binary disk files, that is ones that can be read and written by both big-endian and little-endian platforms.
... output is written in big-endian order (high-order byte first), as this is traditional network order.

nsIEffectiveTLDService

... url display and dispatching - in order to perform network operations such as downloading new mail, copying and moving messages, and displaying messages from a remote server, the url system interacts with necko and reflects it's state to the mail window.

Constants - Plugins
npres_network_err 1 stream failed due to problems with network, disk i/o, lack of memory, or other problems.
... npres_user_break 2 user canceled stream directly by clicking the stop button or indirectly by some action such as deleting the instance or initiating higher-priority network operations.

Plug-in Development Overview - Plugins
for example: image/xbm:xbm:x bitmap or for 2 mime types: image/xbm:xbm:x bitmap;image/png:png:portable network graphics.
... working with urls the plug-in api provides methods that plug-ins can use to retrieve data from or post data to a url anywhere on the network, provide hyperlinks to other documents, post form data to cgi scripts using http, or upload files to a remote server using ftp.

Debugging service workers - Firefox Developer Tools
it is also worth knowing that if you are testing an app's offline capabilities, you'll be able to see whether requests are being retrieved from a service worker-initiated cache rather than from the network by looking at network monitor.
... note: there is currently a bug whereby the network monitor cannot show network requests from a service worker running in a different process to the application (bug 1432311).

Source map errors - Firefox Developer Tools
the message looks a little different in this case: in this case, the error will also be displayed in the source tab in the debugger: networkerror when attempting to fetch resource a bug in firefox prevents it from loading source maps for web extensions.
... source-map-fehler: typeerror: networkerror when attempting to fetch resource.

Storage Inspector - Firefox Developer Tools
cookies created as a part of response of network calls are also listed, but only for calls that happened while the tool is open.
... working with the storage inspector the following articles cover different aspects of using the network monitor: cookies local storage / session storage cache storage indexeddb extension storage ...

Tips - Firefox Developer Tools
