问题 How do I prevent Firefox SDK content scripts from loading multiple times? The docs and a bug report I found suggest the contentScriptWhen property should limit the number of times my content scripts are executed, yet I see them running anywhere from twice to 15 times in a page load. Here's what's in my main.js: var data = require("sdk/self").data; var tabs = require('sdk/tabs'); var pageMod = require('sdk/page-mod'); pageMod.PageMod({ include: ['*'], contentScriptWhen: "ready",

问题 I'm developing a new tab page replacement add-on for Firefox. After it's installed, when I click the new tab icon to open a new tab, the new tab opens fine, but the address bar shows a messy URL: resource://firefox_p-at-getblog-dot-com/getblog_buttons_page/data/newtab.html How do I make the address bar empty? 回答1: There are only a few pages that will have "blank" uris in the URI bar. Now, you have a couple of options: Overlay/inject into browser.xul and just add your add-on URI to

问题 I'm programming a Firefox Add-on SDK based extension. I need to use both a left and a right-side sidebar, at the same time . By default, I can display one on the left side. I've already read about changing between having the ui/sidebar on the left and the right by using the CSS: @namespace url(http://www.mozilla.org/keymaster/gat...re.is.only.xul); hbox#browser { direction: rtl !important; } hbox#browser > vbox { direction: ltr !important; } But, that seems to be something of the old-school,

问题 I have an extension, functional on Chrome, that monitors the active Tab for URL changes. Specifically, I need to detect when the URL changes, but there is no new page load or navigation. Some sites do this (e.g. when you click to view another video on YouTube). On Chrome, I accomplished this with: chrome.tabs.onUpdated.addListener(function(tabId, changeInfo, tab) { if (changeInfo && changeInfo.status == "complete") { //do stuff here } }); How do I detect such changes in a Firefox add-on? I've

问题 I am able to grab the URL of an image on a website, but I want to download the image to the local drive. I actually want the standard download prompt. What is the best way to do this using Firefox Addon SDK (using Javascript)? 回答1: So using some code lifted from Firefox's nsIWebBrowserPersist docs, I cobbled this together. I don't understand some of the scope issues involved, and this does not prompt the user for where or how to save. For my purposes, it works, but I would like a better

问题 After hours and hours trying to get things working, I have this error in my console: [CustomizableUI] Widget action-button--myAddonID-misspelutton not found, unable to remove from inner-toolbar-myAddonID-the-title-of-my-addon1 CustomizableUI.jsm:171 So, the addon's widget id is misspelled somehow and stuck somewhere. The term does not appear in any of my code. Details: I originally built this addon using XUL overlays, and am rebuilding it with the Firefox AddOn SDK. I think (but I'm not sure)

问题 I am unable to understand . Why my functions are executed thrice after addition in the firefox extension using "page-mod" . This is my code : [ main.js ] var pageModOptions = { include: ["http://xyz.com/*"], attachTo: ["top", "frame", "existing"], contentScriptWhen: "end", onAttach: function(worker){ worker.port.on("Done", function(elementContent) { console.log("emitted by tarun :" + elementContent); worker.port.emit("start", htmlfilePath); }); }, }; pageModOptions.contentScriptFile = [data

问题 I'm trying to redirect a tab to a new page when the URL matches my pattern before it's done loading. The method I came up with does the redirection after a good part of the page is done loading yet. var tabs = require("sdk/tabs"); var tab_utils = require("sdk/tabs/utils"); function logShow(tab) { console.log(tab.url + " is loaded; " + pattern.test(tab.url)); if (pattern.test(tab.url)) { var lowLevelTab = viewFor(tab); console.log(tab_utils.setTabURL (lowLevelTab, newURL(tab.url))); // also

问题 I'm trying to build a Firefox add-on based on their SDK and I wanna use panel for this. The panel is connected to a widget, so every time I click on the widget icon the panel shows up. My problem is that I want the panel to stay visible even if I click on an area outside the panel and to be able to close only based on a certain situations. Can this be achieved, or the panel API doesn't support this? Thanks 回答1: It can't be achieved through the SDK API. However, you could actually "hack" the

问题 How can I access firefox extension data from javascript code injected directly to the page? I´m looking for something similar to web_accessible_resources key in manifest.json for chrome extensions. I´m building bootstraped (restarless) extension with addon-sdk. When I´m injecting individual scripts into the page from content script it works fine, but when I want to access the resource from page it won´t let me - error message is something like Access to restricted URI denied. . I can also
