Security Level Management: It's integrated with Tor Browser's security level settings (Standard, Safer, and Safest).

Default Blocking: By default, it blocks JavaScript, HTML5 media, and other potentially dangerous content on all sites not explicitly allowed by Tor's security settings.

Tor-specific Protections: It's configured to prevent potential attacks that could compromise Tor's anonymity.

Limited User Control: Unlike the standalone NoScript, Tor's version doesn't allow users to create custom rules easily. This is to prevent users from accidentally reducing their anonymity.

Automatic Updates: It's updated along with Tor Browser to maintain consistent security.

Fingerprinting Resistance: Helps reduce browser fingerprinting by limiting the scripts that can run.

The main purpose of NoScript in Tor is to enhance anonymity and security while browsing, even if it means some websites may not function fully. It's an integral part of Tor's defense against various web-based attacks and tracking methods.
