How do I change Tor version?
UPDATING TOR BROWSER MANUALLY
Remove Tor Browser from your system by deleting the folder that contains it (see the Uninstalling section for more information). Visit https://www.torproject.org/download/ and download a copy of the latest Tor Browser release, then install it as before.
How do I download original Tor Browser?
The safest and simplest way to download Tor Browser is from the official Tor Project website at https://www.torproject.org/download. Your connection to the site will be secured using HTTPS, which makes it much harder for somebody to tamper with.
Why is my Tor so slow?
Tor circuits lengthen the connections
So instead of connecting directly to the destination server, a connection is made between each relay of the circuit and this takes more time. Furthermore, Tor tries to build circuits with relays in different countries which make connection travel more and appear slower.
