            How do I check if my browser has JavaScript enabled?
        
            You normally do this by checking your browser's options. This will 
            depend on the browser you're using. Instructions for some of the more common 
            browsers are below:
        
            Internet Explorer:
        
            - Go to Tools from the top menu
 
            - Select Internet Options
 
            - Click on the Security tab
 
            - Click Custom Level
 
            - Scroll down until you see the Scripting section
 
            - Ensure that the Active Scripting option is set at Enable
 
            - When the Warning! window asks Are you sure you want to change the 
                settings for this zone? click Yes
 
        
        
            Mozilla Firefox
        
            - Go to the Firefox menu
 
            - Select Options
 
            - Select the Content tab
 
            - Check the Enable JavaScript checkbox
 
            - Click OK to close the Options window
 
        
        
            Google Chrome:
        
            - Go to Chrome from the top menu
 
            - Select Preferences...
 
            - Click on Show advanced settings... Click on Content Settings...
            
 
            - Ensure that the Allow all sites to run JavaScript (recommended) option is 
                selected
 
            - Click OK
 
        
        
            Apple Safari:
        
            - Go to Safari from the top menu
 
            - Select Preferences
 
            - Select Security
 
            - Ensure that the Enable JavaScript option is checked
 
            - Click OK
 
        
        
            Opera:
        
            - Go to Menu from the top menu
 
            - Select Settings
 
            - Select Quick Preferences
 
            - Ensure that the Enable JavaScript option is checked
 
        
        
            Netscape Navigator:
        
            - Go to Edit from the top menu
 
            - Select Preferences
 
            - Select Advanced
 
            - Select Scripts & Plugins
 
            - Check the Enable JavaScript checkbox
 
            - Click OK
 
        
        
            
                Depending on your browser, the exact steps may differ slightly from above. 
                Having said that, the above steps should point you in the right direction.
         
        
            
                Note that you may need to refresh the page after enabling JavaScript before you 
                see the effect.
         
        
            How do I disable JavaScript?
        
            You simply go through the steps above but ensure the JavaScript options are not 
            checked/selected.
        
            If you're developing web pages with JavaScript, it's good practice to view your 
            website with JavaScript disabled. This will show you what your website will look 
            like to users who choose to disable JavaScript.
        
            Other browsers?
        
            Most (if not all browsers) give you the option to enable/disable JavaScript. If 
            your browser is not listed above, the steps above will give you some idea of how 
            to find it. Just look for something called tools, options, 
            preferences or something similar.
        
        
            Warning
        
            Java and JavaScript are two different things - make sure you're 
            enabling/disabling the right option!
