Javascript is something to do with displaying graphics on websites, is it? How and what are the hacks that you are describing?
Thx
Sorry

I'll explain.
NoScript is an add-on to Firefox browser that disables javascript by default. Yes, Javascript is required for most sites to work, but it's also used by the bad guys to hack your session, steal cookies, impersonate you etc. The Noscript add on blocks ALL javascript by default - even the good ones (which you can selectively turn on on a one-time basis or permanently). For examply I've granted permanent access to all google, facebook, flickr javascripts since those are sites I trust. This might be a bit of an inconvenience, but for the security conscious, this is a boon (something I believe must be made mandatory for all browsers). You can enable javascript selectively when you reach a site and block all those annoying banner ads, third-party scripts that collect your personal info etc. Just enable the scripts from the site you are browsing on. Use it for a few weeks and you'll get the hang of it. When you browse to an unknown site, you can be assured you're browsing safely and turn on JS if you feel it's safe to do so.
Caveat: This wouldn't be for everybody; some find it annoying and don't care about security. If ur that person it's not for you; but it'll make for a safer, faster browsing experience.
There's lots more it can do than what I've described here. More info here:
