hello, i have a lot of problems detecting active extensions on browser and i was spending a lot of time to search on google to find solution and i found 2 solutions:
first solution
second:
var detect = function(base, if_installed, if_not_installed) {
var s = document.createElement('script');
s.onerror = if_not_installed;
s.onload = if_installed;
document.body.appendChild(s);
s.src = base;
}
var log = function(msg) {
document.getElementById('log').value += '[*] ' + msg + '\n';
}
function logme(i, id) {
return function() {
log('Detected addon: ' + i + ' (' + id + ')');
}
}
window.onload = function() {
var xhr = new XMLHttpRequest();
xhr.open('GET', 'addons.json', false);
if(xhr.status == 404) alert("ok");
xhr.onreadystatechange = function() {
if (xhr.readyState == 4) {
var addons = JSON.parse(xhr.responseText);
for (var i in addons.prob) {
detect('chrome-extension://' + addons.prob[i].id + addons.prob[i].fajl,logme(addons.prob[i].ime, addons.prob[i].id));
}
}
}
xhr.send(null);
}
addons.json:
{
"prob":[
{
"id":"elicpjhcidhpjomhibiffojpinpmmpil",
"ime":"Video Downloader professional",
"fajl":"/startpage/hu/L64P.js"
},
{
"id":"mpfambnfjgnnbmldefnhdjinogehhjem",
"ime":"web developer",
"fajl":"/manifest.json"
},
{
"id":"jffbcpkfdlpegbadfomimojhgaaoaeed",
"ime":"moviepie",
"fajl":"/logo128.png"
}
]
}
but for both scripts i have the same problem. some extensions doesen't allow to access file or image from source if is not named in web_accessible_resources (manifest.json) and i get error like this:
Denying load of chrome-extension://mpfambnfjgnnbmldefnhdjinogehhjem/manifest.json. Resources must be listed in the web_accessible_resources manifest key in order to be loaded by pages outside the extension.
