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.

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?

greatly appreciate any insight

The thing is, though, JavaScript is self-modifying. So we should be able to find a way to change what certain functions do without recompiling the browser and removing the implementations entirely from the JavaScript engine.
