Reinstalled the operating system, installed Maxthon 7.1.7.8000, which I had been using before. Logged into my account, synchronized the data and everything was fine. But after a few minutes, the browser itself updated to version 7.3.1.6201. The new browser stopped opening the sites that I constantly used, constantly giving an empty window with the message "ERR_CONNECTION_RESET". Even the site https://www.maxthon.com/ stopped opening. I deleted this browser and reinstalled it immediately on 7.3.1.6200 (which I downloaded through Edge)). An attempt to log into my account shows endless synchronization or does not accept my login / password at all, a red message "network error" appears. At the same time, my bookmarks / passwords / quick access are not available. Now I tried to download and install 7.3.1.7800 beta, the problem remains. There is Internet access, but there is no access to my data.
