Question

navigator.plugins in javascript provides the plugins-array for the browser. Is it possible to set this array to null? I tried that(navigator.plugins = null;) but it was not setting to null. Also, I tried to set it to an empty array(navigator.plugins = new Array();)

Also if this is possible, is this a good practice?

Answer 1

In Chrome, it is possible to do this by setting window.navigator to null. However, I’m not sure why you would do this. Since you’re dealing with JavaScript, it would be possible for someone to use a debugger to stop your code from running and intercept this code before you’re able to set it to null.

Moreover, the navigator object generally contains information about the client machine, and if I’m the user, I most likely know more about my computer than your server does, so disabling this wouldn’t really have any measurable advantage that I can see.

Also, this would have to happen on every pageload.

Finally, I don’t know how other browsers would handle this, but you very well may run into trouble trying to do this in other browsers.

In short, I don’t think it’s a good practice; however, you didn’t provide details on why you want to do this. Without that information, I cannot give you a fair answer other than it’s not a good idea. So you’ll of course need to examine why you want to do this and determine if it’s really worth the hassle.
