I usually have a fast connection and reasonable data limits available, so I don&#x27;t worry too much about how much stuff my browser needs to pull down to render a website.  However, there&#x27;s another type of bloat that absolutely kills my browser and that is all of the JavaScript.<p>One of my computers is a netbook-ish Lenovo x131e from a few years ago.  It runs everything I need it to very well, except for web browsing in Firefox.  Many pages cause the browser to completely choke for a few seconds while the JavaScript does its thing.<p>I finally broke down and installed NoScript and it feels like I&#x27;m browsing the web on a brand new computer!  Pages load fast and render quickly.  If JavaScript is required, I can enable it on a site-by-site basis.  There&#x27;s also the privacy and security benefits, but my main issue was performance.<p>I used to think that people who browse with JavaScript disabled were being silly, but now I understand why someone would want to do that.<p>I know that part of the problem is Firefox and part of it is the under-powered computer.  Browsing the same sites in Safari on a 6-year-old MacBook Pro isn&#x27;t nearly as painful and, generally speaking, I leave the JavaScript alone on that computer.
