Support for extensions using XUL/XPCOM or the Add-on SDK has been removed in Firefox 57, released Nov 2017. As there will be no supported version of Firefox enabling these systems, this page will become eliminated by December 2020.
JSON representation of searching Facebook public posts We can use the object model API to get names and their public posts about the term java. In the Listing 3, lines 1 through 3 lines create JsonReader; line 5 creates JsonObject for the results; line 7 loops over each result; and lines 8 through 11 get the name of the person who posted, get the public post, and prints them. Creating a default package.json file. To create a default package.json using information extracted from the current directory, use the npm init command with the -yes or -y flag. On the command line, navigate to the root directory of your package.
Add-ons making use of the strategies explained in this document are considered a legacy technology in Firefox. Put on't make use of these techniques to develop fresh add-ons. Make use of WebExtensions instead. If you preserve an add-on which uses the techniques described right here, consider migrating it to make use of WebExtensions.
Beginning from Firefox 53, no fresh legacy add-ons will end up being accepted on addons.mozilla.org (AMO) for desktop Firefox and Firefox for Android.
Beginning from Firefox 57, just extensions developed making use of WebExtensions APIs will become backed on Desktop Firefox and Firefox for Google android.
Even before Firefox 57, modifications arriving up in the Firefox system will split many legacy extensions. These modifications consist of multiprocess Firefox (at the10s), sandboxing, and several content processes. Heritage extensions that are affected by these adjustments should migrate to use WebExtensions APIs if they can. Observe the 'Compatibility Milestones' record for even more details.
A wiki web page containing resources, migration pathways, office hours, and even more, is available to help developers changeover to the fresh technology.
The
package.json
file contains express information for your add-on, giving not only descriptive details about the add-on for presentation in the Add-ons Supervisor, but other metadata required of add-ons.Some of its posts, like as
icon

are usually created into the install manifest when the add-on is usually built usingjpm xpi
.Others, like as
lib
,permissions
, andchoices
, signify instructions to the jpm device itself to generate and consist of particular program code and data structures in your add-on.Creating a manifest
The
package.json
