问题 I'm now using the new version of the Jetpack API of which allows you to create addons for Firefox using a JS framework. The 'panel' object is easy to use - but I'm struggling to find a way to position it.

问题 I am busy developing a firefox extension. I am using the Add-on Builder What it will do: Get an ID from a PHP page (XMLHttpRequest) Call another function and send that ID with it That function inserts CSS with a link tag created by javascript My Problem: It won't work. If I alert the currenttheme variable, nothing happens. So the XMLHttpRequest doesn't seem to work. My code: main.js: var Widget = require("widget").Widget; var tabs = require('tabs'); exports.main = function() { var pageMod =

问题 I'm crawling about 20 Web sites in the background, when a page loads, within the addon script, with the page-worker. Unfortunately the browser freezes, unpredictable during that time. I tried to use timers.setTimeout(..., 0-400ms) and also tried the example from the wiki function executeSoon(aFunc) { var tm = Cc["@mozilla.org/thread-manager;1"] .getService(Ci.nsIThreadManager); tm.mainThread.dispatch({ run: function () { aFunc(); } }, Ci.nsIThread.DISPATCH_NORMAL); } but this also freezes the

问题 I would like to add another icon to the Firefox addon I develop than the standard Icon: I use the firefox-addon-sdk jetpack to develop it 回答1: You have to add it to your package.json . That file is initially generated in your add-on's root directory the first time you run cfx init . This will add an icon (assuming the add-on's directory is "my-addon"):` { "name": "my-addon", "title": "my-addon", "id": "jid1-1FERGV45e4f4f", "description": "a basic add-on", "icon": "icon.png", "icon64": "icon64

问题 I'm working on an update to my "jump-to-anchor" add-on which is a Firefox add-on to let you right-click somewhere in a doc to (hopefully) get the closest anchor above the click point. After submitting the add-on, I realized I could improve the algorithm by finding the actual text node where clicked, and look up from there (instead of the first children of the current clicked element). However, in my tests (against a page I happened to be reading, http://tools.ietf.org/html/rfc5323#section-2.3

问题 Are you able to access your file-system, using Jetpack, and do operations such as creating or reading files or saving images? 回答1: The Add-on SDK 1.0b5 (the most recent version at this moment) has a file module for this purpose. Note that it's not a high-level module, meaning it can change incompatibly in future Add-on SDK versions. [the original answer from 2010/01] No, there's no jetpack-specific APIs for this yet, note the red link on MDC and the lack of a "JEP" about this. You're not

问题 Developing a Firefox Add-on. Anyone can please help to figure out how to make a Panel transparent. Here is the code to show a panel: var panel = require("sdk/panel").Panel({ width: 570, height: 250, contentURL: require("sdk/self").data.url("test.html") }); panel.show(); 回答1: I found a solution, but it isn't pretty since sdk/panel.js doesn't seem to expose the raw Panel object in order to tweak/extend or compose a another Panel from the existing one. Here goes: (1) Get the source for sdk/panel
