Every Awazon address is a Tor hidden service, and a hidden service only opens in Tor Browser. Install it correctly once and most of the ways a first connection goes wrong are closed before you start.
Download from the official source only
The only place to get Tor Browser is the Tor Project website. Any other download is either an unverifiable mirror or a modified build with something added you do not want. If a download page is not the official project, close it.
Verify the signature the first time
The Tor Project signs every build. Verifying that signature against the project key the first time is the difference between a clean browser and one that quietly leaks around Tor. The download page walks the check for every system.
Set the security level to Safest
Open the shield beside the address bar and set the level to Safest. That turns scripting off everywhere, which removes the most reliable route to break anonymity from inside the browser. Awazon works at Safest, so you lose nothing you need.
Leave the browser as it ships
Do not resize the window, do not add extensions. Both make your browser fingerprint unique, the opposite of what Tor is for. Use it exactly as it comes, then bring a verified address from this board.
