I keep Flash on a short leash with Click To Flash. Further, unless I specifically need it, Java is turned off. However, JavaScript is everywhere and presents unique security, as well as just plain annoying issues of its it own. Here’s a Safari Extension to help you manage what JS runs and what doesn’t.

There’s our take on the Top 10 Safari extensions [and their friends], but new extensions are arriving all the time. For example, Drew Thaler’s JavaScript Blacklist is I believe the first JavaScript management tool for Safari.

Although this ain’t no NoScript, JavaScript Blacklist obviates some of the more annoying uses of JS right out of the box by blocking:

• tynt.com – modifies copy-pasted text
• intellitxt.com – green links with double-underlines
• snap.com – link previews

JavaScript Blacklist is super easy to configure and, moreover, the code has been put into the public domain, so you can do anything you want with it. And, because it written in global.html, this extension is only loaded and compiled once, whereas the injected script is loaded dozens of times on a typical site, saving your precious computer resources and improving security.

Get your very own copy of JavaScript Blacklist here. To install, just go to the Downloads folder and double-click it.

To add domains to the blacklist, simply copy and paste them (no http:// needed) into “Block scripts from” in JavaScript Blacklist in the Extensions preference pane in Safari.
