When you read this article, you must have encountered the same problem as me: after upgrading to Windows 8.1, you found that third-party browsers like Google Chrome, Firefox, 360 Browser, etc. can’t be used and can’t open web pages. I had this problem too, but solved it today. Searched online for a long time and finally fixed it. How?
I installed 360 Safe Guard; in “More” there’s a tool called LSP Repair. Click it, it shows you how many items are abnormal, then click Repair to restore Windows defaults. Fixed instantly. Open your browser again — normal now?
