Is there a way to block browser JavaScript from executing commands that retrieve sensitive information from my local machine, while still allowing JavaScript that is only used for rendering web pages? (lemmy.world)

As a security-conscious user, I've used NoScript since Firefox's early days, but its restrictive nature has become frustrating. I'm often forced to go unprotected just to access websites with multiple scripts running on different domains, which defeats the purpose of using NoScript and balances security and usability that it once provided.

by sensitive information I'm referring to

local machine time
local machine ram
local machine operating system + version
local machine hardware
Serial Number
Hardware ID
UUID
Windows Device ID
Windows Product ID
...

greatly appreciate any insight

EDIT:

could be possible solution

~~LibreJS: GNU LibreJS aims to address the JavaScript problem described in Richard Stallman's article The JavaScript Trap.~~
JShelter: Mitigates potential threats from JavaScript, including fingerprinting, tracking, and data collection. Slightly modifies the results of API calls, differently on different domains, so that the cross-site fingerprint is not stable. Applies security counter-measures that are likely not to break web pages. Allows fine-grained control over the restrictions and counter-measures applied to each domain.

Most of those things cannot be collected through JavaScript.

Local time can.

RAM can only be approximated to protect user privacy. Edit: And it’s not available on Firefox.

OS+version are already in your browser’s user-agent string that is sent out with every request you make.

Machine hardware cannot be enumerated. JavaScript can try to guess your GPU based on what it can do with WebGL.

There is no way to get a serial number or similar.

To spoof timezone/OS+version/browser+version ... and disable WebGL, use https://sereneblue.github.io/chameleon/
