since my Chrome [chromebook] OS is a Linux-based operating system, why cant i install tor? i'm technologically challenged so please be gentle.
Chrome [chromebook] is a surveillance/tracking device made by Google. You can't use it without Google account. You are the product for the ad industry. Exactly opposite what's Tor's mission.
Chromebooks don't natively support the Tor browser.
Alternatively you can either run Tails in live or install another Linux distro via dual boot.
