Disable drag and Text selection in Firefox

Firefox is known to support most of the W3C Dom standards and IE is usually to support most non standard or I would say "IE Standard". Anyways, I still like IE because my website is viewed by mostly IE users, almost over 85%.

I had seen some people copying text from website, so I wanted to implement no drag and copy text from my website. Here is what I added to the body tag of each HTML rendered page on my site. (I know there are other ways to copy. :( )

onmousedown="javascript:clickTrap();" ondragstart="return false" ondblclick="return false" onselectstart="return false"

This stopped drag and text selection for every IE visitor on my site. Easy and simple technique allowed me to achieve what I wanted. Still there were about 15% "Standard Browser" based non standard users. They could drag and select text from my site. Searching paid off after a long time. Mozilla based browsers need to you to create a javascript event handler routine to stop the drop or use this non-standard, browser specific tags. Here is what I did. You can leave them in your CSS file because IE just ignores them and Firefox will block the drag.

<style>
    .protectedText 
    {    
        -moz-user-focus: ignore;    
        -moz-user-input: disabled;    
        -moz-user-select: none;
     }
</style>
<input class="protectedText" type="text" value="Change this"> 
<span class="protectedText">sdaf</span>

Find other such tags, that mught be useful for you.
