You most likely want a host permission for the resource you’re trying to load: https://developer.mozilla.org/en-US/Add-ons/WebExtensions/manifest.json/permissions#Host_permissions
Cross-Origin Request Blocked: The Same
Origin Policy disallows reading the remote resource at
. (Reason: CORS header
‘Access-Control-Allow-Origin’ missing). (unknown)
Hello:
A set
"permissions": [
"*://developer.mozilla.org/*",
"contextMenus",
"notifications",
"storage"
],
I also tried these
"webNavigation",
"webRequest",
"webRequestBlocking"
But same warning:
Is there any way to check a link from a website that points to a
website in another domain?
I try to do an extension to check links to web pages.
I try
to do an extension to check links to web pages (including those
that point to other domains.)
If I can not verify this, the extension will not
work much.
For example
function urlExists(url)
{
var http = new XMLHttpRequest();
http.open('HEAD', url);
http.onreadystatechange = function() {
if (http.readyState == this.DONE) {
http.status != 404;
//document.write("<br>status2: " +
http.status);
console.log("<br>status1: " + http.status);
}else{
console.log("<br>status 404: " + http.status);
}
};
http.send();
}
I need to be able to
check for example:
urlExists();
urlExists();
