Hi, I'm trying to figure out Why my HP Laptop isn't working right. I'm Not able to login to my Foxnews.com Profile anymore for the past several Days & Today I've been in Chats w/Microsoft and they didn't fix anything either. I've also had Over $ xxxx from my Bank Account so, I'm trying to search Everything. I've tried using Internet Explorer & that didn't work either (Actually even Worse than Microsoft Edge that I Usually use). I can also be reached by cell at: [removed] or [removed]. Plz Help if you can? Thanks SOOO MUCH! So, I just checked/right clicked & viewed my "Inspect Element" View Source... & I scrolled & found a few links to Mozilla for some reason & a Bunch of Code stuff. Here are a couple of the Links I found (I Don't even have Mozilla on my Laptop so that's Why I'm Super Confused about this now too. I'm Not Blaming Mozilla for Anything, Simply trying to figure out what happened to my Laptop & Why I Can't Login Completely to foxnews anymore lately??? So, here is a little more of what I copied & Pasted from my Element/Script Block page or whatever you call it. I Hope this Helps??? I Don't know what else to do at this point. I've been using Edge w/Adguard for a Long time now with No Problems until a few Days ago. I also do Not use Chrome but, I Do have it Installed on my Laptop. But, Not Mozilla. I used to before but, Microsoft told me I should use Edge to Work the Best w/my Windows 10 Pro Office... https://developer.mozilla.org/en-US/docs/Web/API/RTCPeerConnection/setConfiguration * WebSocket wrapper implementation. * https://github.com/AdguardTeam/AdguardBrowserExtension/issues/349 * * Based on: * https://github.com/adblockplus/adblockpluschrome/commit/457a336ee55a433217c3ffe5d363e5c6980f26f4 */ /** * As far as possible we must track everything we use that could be sabotaged by the website later in order to circumvent us. */ var RealWebSocket = WebSocket; var closeWebSocket = Function.prototype.call.bind(RealWebSocket.prototype.close); function WrappedWebSocket(url, protocols) { // Throw correct exceptions if the constructor is used improperly. if (!(this instanceof WrappedWebSocket)) { return RealWebSocket(); } if (arguments.length < 1) { return new RealWebSocket(); } var websocket = new RealWebSocket(url, protocols); // This is the key point: checking if this WS should be blocked or not // Don't forget that the type of 'websocket.url' is String, but 'url 'parameter might have another type. checkRequest(websocket.url, 'WEBSOCKET', function (blocked) { if (blocked) { closeWebSocket(websocket); } }); return websocket; } // https://github.com/AdguardTeam/AdguardBrowserExtension/issues/488 WrappedWebSocket.prototype = RealWebSocket.prototype; window.WebSocket = WrappedWebSocket.bind(); copyProperties(RealWebSocket, WebSocket, ["CONNECTING", "OPEN", "CLOSING", "CLOSED", "name", "prototype"]); RealWebSocket.prototype.constructor = WebSocket; }; /** * The function overrides window.RTCPeerConnection with our wrapper, that will check ice servers URLs with filters through messaging with content-script. * * IMPORTANT NOTE: * This function is first loaded as a content script.
