I need to listen to each HTTPS URL in the main frame and examine the URL against a pattern to check if the URL domain match a list item or not. The observer works well in the main page, e.g. https://google.co.uk. But if I tried to click any link inside the page, the loop does not terminate. It sticks in the first iteration. The console gives this error:
NS_ERROR_NOT_AVAILABLE: Component returned failure code: 0x80040111 (NS_ERROR_NOT_AVAILABLE) [nsIDOMWindowUtils.isParentWindowMainWidgetVisible]
This is the main.js code:
function onError(e) {
console.log(e);
}
// This function to test the intercepted URLs
function calbackFun(request) //The function will be passed request details. We use the target URL.
{
var request = request.url;
console.log("Request is: " + request);
var found=false;
var record = ["google.co.uk","facebook.com"];
var x=0;
for(rec of record)
{
console.log("loop" + x);
var pattern = "(https:\\/\\/)(.*\\.)*"+"("+rec+")"+"(\\/.*)*(\\/)*";
console.log("pattern is: "+pattern);
if(request.search(pattern) == 0)
{
console.log("Match");
found=true;
break;
}//end if
else
{
console.log("No match");
}//end else
x++;
}//end for
//after the loop
if(found == false)
{
console.log("no match in the whole list");
}//end if found==flase
}//end calbackFun
browser.webRequest.onBeforeRequest.addListener(
calbackFun, //callback function
{urls: ["<all_urls>"],
types: ["main_frame"]}, //urls in the main address bar
["blocking"]
);
This is manifest.json:
{
“manifest_version”: 2,
“name”: “testHTTPObserver”,
“version”: “1.0”,
“description”: “No description.”,
“background”: {
“scripts”: [“main.js”]
},
“applications”: {
“gecko”: {
“id”: "addon@example.com"
}
},
“permissions”: [
"<all_urls>",
“activeTab”,
“tabs”,
“storage”,
“webRequest”,
“webRequestBlocking”,
“webNavigation”
],
"browser_action": {
"default_icon": {
"64": "icons/warning.png"
},
"default_title": "testHTTPObserver"
}
}
Can you please point out to me how to resolve this issue? I need to check/examine each URL that pass through the main address bar.
