[Eug-lug] How secure is Javascript?

[Allen Brown]

I am moderately paranoid about allowing web sites run javascript
in my browser.  (I use NoScript in Firefox.)  Basically I only
enable it if I know the owner of the site or trust them because
of who they are.  Examples: personal friends or banks.

Am I being unnecessarily paranoid?  Has Javascript gotten good
enough that I can let my guard down?  How do you all handle this?

   Criticism may not be agreeable, but it is necessary. It fulfils
   the same function as pain in the human body. It calls attention
   to an unhealthy state of things. --- Sir Winston Churchill
