问题 I have a basic Google Chrome extension which needs to be ported to Firefox. I uploaded the .crx file to the Firefox marketplace and it got accepted but is under review rightnow. I downloaded the the generated xpi file and tried to install it locally but without any success. It tell that the plugin is invalid or corrupted. Another method that I tried is I ported the extension using chrome-tailor and generated the xpi. I am able to install the extension in this but the content scripts are not

问题 I'm trying to write cross browser Web Extension. Based on selected value on web page I want to create appropriate entry in context menu. I created a sample code to check if browser is entering to Event Listener. In Chrome it's all working fine, but in firefox following code is not being executed. console.log("Content script entry"); document.addEventListener('selectionchange', function() { debugger; console.log("CS Add Event"); }); Could you please help? Best regards Frank 回答1: I believe

问题 Created a webextension for firefox (currently using Nightly 52), that uses native messaging to launch a java program on Linux (Ubuntu 14, 32x). The webextension loads, reads the .json file and reads the path which points to a script that starts the java program. The JSON and the path are correct as when I use: var native = browser.runtime.connectNative("passwordmanager"); console.log("native.name" + native.name); //outputs passwordmanager. native.onDisconnect.addListener(function(m) { console

问题 I'm transforming my SDK-based Firefox extension to WebExtensions and I've come to the issue of updating the extension. The current extension is hosted on my own domain (which is an HTTP domain), along with the update.rdf file. Now, for SDK-based add-ons, updates were possible via HTTP as long as the update manifest was signed using the McCoy tool and the valid hash of the update file was provided in the manifest. In addition to that, install.rdf would hold the public key portion of the key

问题 Everything below works in a Chrome extension but silently fails when ported to Firefox on: loading the test.html unless I remove <style></style> from it appending the #test_element to the body Do styles have to go into a separate file for Firefox extension? Why does append() fail? test.js $(document).ready(function() { $.get(chrome.extension.getURL('/html/test.html'), function(data) { // not called unless style element is removed from HTML // and never actually appended if it is removed $

问题 I am working on a Firefox WebExtension which has a popup and uses chrome.storage.local to store state. So far, I have got it to store data for specific tabs using the tab id. I would like to reinitialize the local storage if the current tab is reloaded. This is because the extension may have made some changes to the DOM which will be lost if the tab is reloaded; what state it has stored is therefore incorrect. The initial JavaScript code is called from the popup. How can I run some code when

问题 I am trying to port a chrome extension to firefox using the relatively new WebExtensions from Firefox. I always getting the following error Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at .... (Reason: CORS header 'Access-Control-Allow-Origin' missing) I added the website i would like to access to the permissions section inside the manifest.json like explained on the website, and also on Google Chrome its working. Normally it should work that way,

问题 I just noticed that the tabs API is only available for the desktop not for Android. In the past I have used this code to send messages to my content scripts: sendMsgToTabs(msg) { return browser.tabs.query({}).then(tabs => { let msgPromises = [] for (let tab of tabs) { let msgPromise = browser.tabs.sendMessage(tab.id, msg) msgPromises.push(msgPromise) } return Promise.all(msgPromises) }) } But how am I supposed to do that when the tabs API is not available? I mean the only thing I can think of

问题 I want to use some database in my Firefox web extension, I already found this, but it's just a storage for key-value pairs. So how can I use database in the Firefox web extension? 回答1: You can use the IndexedDB Web API: https://developer.mozilla.org/en-US/docs/Web/API/IndexedDB_API There's a sample extension that uses it, though it's using a library. It might be better to look at general Using IndexedDB examples. You probably want to declare "unlimitedStorage" permission; in Chrome, it lifts
