Advanced JavaScript Settings in Firefox

JavaScript TweaksFirefox allows for you to specify a few things that JavaScript can and can not do, but you must edit it under the advanced JavaScript settings. The steps to get there are pretty simple, but for those of you who don’t know – here is another way you can get a little more control over Firefox and how the browser handles JavaScript commands.

To get to the Advanced JavaScript settings, follow these steps:

  1. At the top of the Firefox window, click on the Firefox button and then select Options
  2. In the Options window, select the Content panel.
    1. Enable JavaScript: Select this option to permit JavaScripts to execute on your computer.
    2. To change advanced settings, click Advanced….

Now that you are there, let me explain what each of these settings mean:

  • Move or resize existing windows: To prevent JavaScripts from changing the position or size of existing windows, deselect this option.
  • Raise or lower windows: This option allows sites to place windows below or above existing windows.
  • Disable or replace context menus: When you right-click an item, a sub-menu may appear. This menu, called a “context menu,” can be disabled through JavaScripts. To prevent them from disabling context menus, deselect this option.

There you have it.  I hope this insight on how you can edit a few basic ways your browser interacts with JavaScript. I really wish Firefox would add more control, however this is a good way to edit a few basic things.

    Firefox 20.0:

    It does not say: Move or resize existing windows

    Instead it says: Move or resize pop-up windows
