When you play games or watch videos on the Internet, you usually do so on a web page. Many sites, like YouTube, offer to change the size of the video to other predefined sizes on the screen or to full-screen. None offer options to resize the games or videos gradually on the screen.

That's what the Firefox extension LmnPopVideo helps you with. The extension makes many HTML elements detachable from the browser. It works well with videos, games and other Flash contents, and may work with other HTML elements as well.

Here is how it works. You first need to download and install the add-on from the official project website over at Mozilla. The extension is compatible with all versions of the browser from Firefox 3.6 on.

Once installed the browser needs to be restarted. The functionality at this point is then fully available in the browser. You can now detach supported HTML elements by moving the mouse cursor over them and clicking on the appearing camera icon in the upper right corner of the element.

When you click on the button, the element is detached from the browser and launched in a separate window where it works in the very same way. Well, the difference is that the separate window is resizable which means that you can adjust the size of the video or game to suite your screen and needs.

Keep in mind that not every element is resizable in the new window. It works well if you detach YouTube videos but for instance not for Kongregate games. The games are still playable on the detached screen.

If you hover your mouse over the top of the detached window you will see a small menubar appear. Here you can access the extension's options, attach it again to the original browser window, reload the video, switch to the default size of it and set the window to top.

The standard controls of the element may be displayed as well. The YouTube controls when hovering the mouse over the window appear so that it is possible to change the volume, pause the video, change the quality or switch to another video position.

The add-on's options offer a few customization options. You can for instance limit the number of detached popup windows to one, make the extension close the original tab automatically or change where in Firefox the extension's links and contents are displayed.

LmnPopVideo is a great Firefox add-on for users who want more control over media elements in the browser. An option to always detach videos, games or music on specific sites would come in handy.

Update: The add-on is no longer available in the Mozilla Add-On Repository. Pop Video is an alternative for Firefox with the same functionality.
