How to Prevent Right Clicking in Firefox
When using Firefox or other Web browsers, visitors of your website can perform a variety of actions by right clicking on your Web page. This includes downloading images by using the "Save Image As" command, or viewing the HTML code you used to create your website by using the "View Page Source" command. Disabling the right click function on your website is the only way to prevent people from being able to right click on your Web page in the Firefox browser.
