firefox-addon-sdk

问题 I have made my full FF extension, and there is a button in the URL bar. The boss now wants the button to show a certain string when you hover over it. Here is my current code for the button: var loadURLButton = function(doc, urlBtnClick) { var urlBarIcons = doc.getElementById('urlbar-icons') var btn = doc.createElement('toolbarbutton'); btn.setAttribute('id', 'urlbutton'); btn.setAttribute('image', require('sdk/self').data.url("canNone.png")); btn.addEventListener('command', urlBtnClick,

问题 I've create a Firefox addon using the addon sdk. I'm trying to use the canvas drawWindow function. I've got the following code to use the function, where ctx refers to a canvas context, that I got with canvas.getContext("2d") . ctx.drawWindow(window, 0, 0, 100, 200, "rgb(255,255,255)"); When I run this code, within a script that is attached using tabs.activeTab.attach({ contentScriptFile: data.url("app.js") // app.js contains the above line of code }); I get the following error: TypeError:

问题 I'm developing this extension https://builder.addons.mozilla.org/addon/1022928/latest/ The code central to this question is in Data/panel.js And it's working pretty well, except that whenever I hit "Gem" to post a jquery call, it just hangs at the loading icon, I don't get any feedback in the console as to why the call is not going through and being processed as it should. So how do I debug that with the new firefox add-on sdk builder beta. I've tried writing to console.log(), and I've read

问题 Supposed my add-on has to access a Javascript variable from a webpage. Let's take https://mozilla.org. There is a global variable called optimizelyCode . My addon will only work if this variable is accessible. How do I let my pageMod do that? To experiment, here are some tutorial scripts: var widgets = require("sdk/widget"); var tabs = require("sdk/tabs"); var widget = widgets.Widget({ id: "mozilla-link", label: "Mozilla website", contentURL: "http://www.mozilla.org/favicon.ico", onClick:

问题 Is it possible to grab user's selected text within Hotkey 's scope? Defined in Addon/lib/main.js : var showHotKey = Hotkey({ combo: "accel-f1", onPress: function() { Addon.saveText(window.getSelection().toString()); } }); Error .. error: Addon: An exception occurred.

问题 Is there a way to access Html5 file api in Fire Fox addon sdk in the content script? This is needed in order to store user added words and their meanings. The data can grow large and so local storage isn't an option. window.requestFileSystem3 = window.requestFileSystem || window.webkitRequestFileSystem; gives me the error TypeError: window.requestFileSystem3 is not a function . I am asking this because i am porting this code from a Google Chrome Extension which allows accessing the file api

问题 For an SDK add-on, I am trying to detect, on right-click, the closest page anchor (as described here). Since JavaScript apparently has no way to query the mouse coordinates without first creating a mouse event listener, and since I don't want an expensive mouseover listener running all of the time on every single page! (and polling to rebuild a mouse listener is ugly and not fully accurate anyways), I was hoping I could get the mouse coordinates from a click event. Unfortunately, although

问题 With the coming of multi-process Firefox I have decided to re-write my addon using the Addon-SDK. My addon is mainly a toolbar with an extensive set of menus. The addonsdk does not provide any way to build menus. So I found this method by which I can add them to an existing toolbar. However, I cannot find any way to create menus like this and add them to an Addon-SDK toolbar. So I thought I would just create the toolbar the same way I am creating the menus. So, I am basically trying to create

问题 I am attempting to add a function to my Firefox extension to trigger an event to delete cookies from site B when a button on site A is clicked. Site A and B do not share a domain but site B is running in an iframe injected into site A.
