问题 I need to turn alert notification off by my extension. The alert function is a javascript built-in function and i override it like below in content script but it still works. content script: window.alert = function(){} It does not turn it off. The problem is realy simple but it does not work and i am going crazy :) manifest.json: "content_scripts": [ { "js": [ "assets/js/jquery-1.12.4.min.js", "assets/js/common.js", "assets/js/handlers.js" ], "matches": [ "http://*/*", "https://*/*" ], "run

问题 In my extension I want to use my own WebAssembly module. After loading my module (to background.html , or popup.html ), I catch the compile error: CompileError: WebAssembly.compile(): Wasm code generation disallowed by embedder. Are wasm modules not supported in Chrome Extensions? 回答1: It seems from this issue that Chrome requires script-src: 'unsafe-eval' CSP directive be active for WebAssembly compilation. See this discussion as to why this is the case, at least for now. Chrome Extensions

问题 background.js: chrome.webRequest.onBeforeRequest.addListener(function (details) { console.log(details.url); window.location.href = 'http://time.com/'; }, {urls: ['<all_urls>']}, []); It shows all requests in the console when I visit a web site, but it doesn't redirect the site to time.com. Additional Information: I got error on background console here: Error in event handler for webRequest.onHeadersReceived/1: ReferenceError: url is not defined at chrome.webRequest.onHeadersReceived

问题 So I am developing a chrome extension. I am trying to get the Youtube video current playing time I am aware that there are many similar questions asked in other posts, but none of their code works for me My code is like this, I have to inject my code to the content script first chrome.tab.query({highlighted: true}, tabs => { tab = tabs[0] chrome.tabs.executeScript(tab.id, {code: "temp = document.getElementById('movie_player'); alert(temp); alert(temp.getCurrentTime());"}, respond => {}); } So

问题 I have set up that when I click extn icon - my extn index.html opens. If I click the icon a second time - I don't want it to open a second tab; I want it to focus the already open tab (if it's open). The problem is with if it's open part. Ideally, I would not want to ask for a tabs permission, as it is very intrusive. Because of this restriction I cannot iterate all the open tabs and check their urls. I tried storing extn tab id in chrome.local.storage and checking for it when I click the

问题 I have an extension with a background page, and by default this causes Chrome to persist after you close all windows, and puts the Chrome icon in the system-tray. I would like to avoid this -- I do not want my extension to cause the Chrome process to persist after closing all Chrome windows, nor do I want to cause Chrome to appear in the systray. According to the only docs I could find on this indicates that the user can set this option globally across all extensions, but that isn't what I'm

问题 I'm trying to enable vue-devtools in Google Chrome. But I cannot enable it. I'm using vue.js inside the Laravel application. My server runs using php artisan serve command. 回答1: If the page uses a production/minified build of Vue.js, devtools inspection is disabled by default so the Vue pane won't show up. To make it work for pages opened via file:// protocol, you need to check "Allow access to file URLs" for this extension in Chrome's extension management panel. I had to restart the chrome,

问题 I wrote a Firefox extension that reads the clipboard and if it has some PEM certificate, it will print it's details in a new tab. I'm trying to port to Chrome. It does not work. What am I doing wrong? I asked for the clipboardRead in manifest.json and I run this in background script and it works fine in Firefox. navigator.clipboard.readText().then(function (textFromClipboard) { //do stuff with textFromClipboard }); This fails in Chrome with "Failed to execute 'readText' on 'Clipboard':
