With the security issues involving your web browser these days, such as drive-by downloads, and other malicious attacks, it is important to do as much as you can to secure your browser. One thing that can be done, to help block a common avenue of attack, is to install a JavaScript blocker.
While it used to be that one could disable JavaScript, so many sites these days rely on it, that disabling it is no longer feasible. By using a blocker, one can selectively enable JavaScript only where needed. The methodology is to install the blocker, which normally disables JavaScript at all sites. Of course, you then start seeing sites that are not functioning properly due to JavaScript blocking. When that happens, you can enable JavaScript only for that site. Or, more to the point, only for the scripts on that site that are required. You will be surprised at the number of JavaScripts that many sites run, which are not directly related to what that site is doing.
A site may be running 10, 15, 20, or more, JavaScripts, of which only one or two may need to be enabled to get the site functioning. The rest are feeding your data to ad sites, and other data trackers, all without informing you.
Adding a JavaScript blocker to your browser varies by the browser you use. You may find it by looking at the available plugins for your specific web browser, or you may need to use a search engine to find one that works for your browser. It is worth it to spend a bit of time searching out, and implementing, a blocker. Once you get used to it, it only takes a few seconds to grant the needed functions on a web site, while leaving non-essential scripting blocked.
