Tor browser allows you to browse the Internet anonymously. I have been using this since a year now and recently I faced the problem that the browser stuck while loading mostly on "loading authority certificates" and "loading network status". I did uninstalled reinstalled it couple of times nothing helped me and finally the solution was simple and I will be sharing the same here.
In my case it is my CMOS battery my battery isnt working and the clock of laptop resets every time I restart . So, what i did was just tuned the time and started the Tor and its in now in to deep web . So the solution is to checkout your clock time of your device.
