I have been wanting to talk about this for a while.
For those of you who are big into security, say hello to noscript!
NoScript is a plugin that installs into firefox. (FireFox is a web browser)
NoScript Blocks all script unless you ok it. (A few sites already added, such as google.)
I use it to allow the webpage i want to run their scripts, but not the advertisement sites that accompany some of them.
Besides a defensive tool, it kind of teaches you, you'll be amazed at just how many places you are actually connecting to whe you go to a webpage.
You can download FireFox here:
And then download Noscript here:
One last thing, if you notice parts of a webpage arent loading properly it's probably because that website is blocked. After noscript is intalled, on the bottom right of firefox's windows will be a S with or without a slash through it, click on it, and "allow" that website.
