Previously, I could write an addon for personal usage packed as something.xpi and I clicked on it to install it. After a while, mozilla introduced xpinstall.signatures.required which you could still get around it. However, it did not stop stabbing developers who are interested to have a personal addon isolated from the world. Today, only web extensions are working and my XUL based addon is thrown away. The tutorials only talk about temporary installation of a web extension while I want my one runs on firefox forever. Beside whether I can use web extension to write into files or create a GUI in

I am trying to execute a script that shows a green border on the specified tab (by ID). The script should execute when the response for the requested URL is an error. The problem is that, when I load the extension from about:debugging , I get the following error (in the browser console in FF 53): Error: No window matching {“matchesHost”:[“<all_urls>”]} I searched for hours and hours and looked at several posts for similar problems but none of them have helped me. For example, this post suggests adding "<all_urls>" permission and it did not help in my case. Another post says that it is not

I'm working on a Firefox add-on to intercept HTTP requests and extract the cookie. I was able to extract 'User-agent' from the header but was unable to extract the cookie. The code I used is below. chrome.webRequest.onBeforeSendHeaders.addListener(function(details){ var headers = details.requestHeaders, blockingResponse = {}; for( var i = 0, l = headers.length; i < l; ++i ) { window.alert("Checking headers"); if( headers[i].name == 'Cookie' ) { headers[i].value = 'twid=notsecret'; window.alert("Cookie Changed"); console.log(headers[i].value); break; } } blockingResponse.requestHeaders =

Currently I am building a webextension on firefox 47. When you click a webextension button, a drop-down menu appears, from there I can navigate to other websites. The button that is appearing is the icon I specified in manifest.json . I wonder if there is any way to change the icon of the extension to a text-string containing the URL I am currently visiting, and changes every time I visit a new URL. No, you can not directly change a browser action or page action icon into some long string of text. You can: Browser Actions : Change the icon using browserAction.setIcon() . This changes the image

I'm trying to create URL inspector using Firefox native messages. The problem is, when native application sends a verdict, onBeforeRequest listener already released request, thus redirection doesn't happen. Can you please help to make my extension wait for reply for up to 2 seconds and redirect the request if answer is "0"? var port = browser.runtime.connectNative("ping_pong"); function inspectURL(requestDetails) { console.log("Loading: <" + requestDetails.url + ">"); port.postMessage(requestDetails.url); console.log("Posting complete <" + requestDetails.url + ">"); } port.onMessage
