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)

Original question by @happeningtofry99158@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.

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?

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
