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

I wish tools like ad-block would allow everything to download in the background but just block things like ads from rendering. That would prevent ad block detectors from knowing they are being blocked,

That defeats the privacy and bandwidth reasons you'd want to use uBlock but that's close to the operating idea of AdNauseam.

how does ad render in the background compromise privacy?

Usual tracking and fingerprinting issues. Would need to sandbox it to make it secure, but that then makes the fake traffic easier to identify. Not worth it in the end.

I'm still bit confused. How rendering could result in fingerprinting? If canvas and other fingerprinting is disabled of course. how is ad render different from rendering other element on a webpage
