/*** [SECTION 2300]: WEB WORKERS
|
||
|
|
A worker is a JS "background task" running in a global context, i.e. it is different from
|
||
|
|
the current window. Workers can spawn new workers (must be the same origin & scheme),
|
||
|
|
including service and shared workers. Shared workers can be utilized by multiple scripts and
|
||
|
|
communicate between browsing contexts (windows/tabs/iframes) and can even control your cache.

/* 2302: disable service workers [FF32, FF44-compat]
|
||
|
|
* Service workers essentially act as proxy servers that sit between web apps, and the
|
||
|
|
* browser and network, are event driven, and can control the web page/site it is associated
|
||
|
|
* with, intercepting and modifying navigation and resource requests, and caching resources.
|
||
|
|
* [NOTE] Service worker APIs are hidden (in Firefox) and cannot be used when in PB mode.
|
||
|
|
* [NOTE] Service workers only run over HTTPS. Service workers have no DOM access.
|
||
|
|
* [SETUP-WEB] Disabling service workers will break some sites. This pref is required true for
|
||
|
|
* service worker notifications (2304), push notifications (disabled, 2305) and service worker
|
||
|
|
* cache (2740). If you enable this pref, then check those settings as well ***/

/* 2304: disable Web Notifications
|
||

|
* [NOTE] Web Notifications can also use service workers (2302) and are behind a prompt (2306)

|
||
|
|
/* 2305: disable Push Notifications [FF44+]
|
||
|
|
* Push is an API that allows websites to send you (subscribed) messages even when the site
|
||
|
|
* isn't loaded, by pushing messages to your userAgentID through Mozilla's Push Server.
|
||
|
|
* [NOTE] Push requires service workers (2302) to subscribe to and display, and is behind
|
||
|
|
* a prompt (2306). Disabling service workers alone doesn't stop Firefox polling the
|
||
|
|
* Mozilla Push Server. To remove all subscriptions, reset your userAgentID (in about:config
|
||
|
|
* or on start), and you will get a new one within a few seconds.
