NoScript on Mac?

I'm aware of the anti-virus software on Mac debate, but how about NoScript?

Should I run NoScript as an add-on in Firefox on my Macintosh or are these javascript exploits for windows only?

 

Javascript exploits are usually browser-dependant rather than OS-dependant. They can control your browser to an extent and extract information. Here's a good example. The executable payloads are usually Windows-only though.

In most scenarios, NoScript is used as a privacy and resource managing tool rather than security. It does that by controlling what javascript is allowed, web bugs, and the like. With click-to-play, you save resources by not allowing those Flash and similar components to run automatically.
