Can't play video on browsers that requires Java plugin

I'm using Macbook Pro late 2011 with Mac OS X Mountain Lion v10.8. I like to watch movie online. Some sites require Java (Applet) plugin to play movies and I couldn't play them.

Below is the steps I solved it:
1). Download and install latest version of Java then restart your browser if it's running.
2). Enable Java applet plugin in your browser. Note that Chrome version 45 no longer supports NPAPI (technology required for Java applet) due to security risk so you cannot play videos on the sites that require Java applet on Chrome anymore. They might use HTML 5 instead to play videos. However, Firefox still support NPAPI so you might consider using it instead. You can enable the plugin by clicking Tools then Add-ons.

3). Add the site to Exception Site List in Java Control Panel. I installed Java 8 and it no longer has Medium security level. There are only Very High and High security levels so Java might block the site by default from using the plugin. Hence, you need to add the site to the exception list. You can go to System Preferences then Java.

4). Open the site or refresh the page and you'll get a popup at the top of the page asking you to allow the browser to run Java plugin for this site. You'll be asked to decide whether to allow it only this time or allow it forever.

5). Refresh the page again. After the page has loaded, it might takes several seconds before the dialog box below shows up.

Check the checkbox then click Run and your video will start playing.
