# Install the Flash plug-in

Flash is a plug-in for your web browser that allows you to watch videos and use interactive web pages on some websites. Some websites won't work without Flash.

If you do not have Flash installed, you will probably see a message telling you so when you visit a website that needs it. Flash is available as a free (but not open-source) download for most web browsers.

## How to install Flash

1. Click this link to launch the Software Center.

2. Read the information and reviews to make sure you want to install Flash.

3. If you choose to install Flash, click Install from the Software Center window.

4. If you have any web browser windows open, close them and then re-open them. The web browser should detect that Flash is installed when you open it again, and you should now be able to view websites using Flash.

## Open-source alternatives to Flash

A handful of free, open-source alternatives to Flash are available. These tend to work better than the Flash plug-in in some ways (for example, by handling sound playback better), but worse in others (for example, by not being able to display some of the more complicated Flash pages on the web).

You might like to try one of these if you are dissatisfied with the Flash player, or if you would like to use as much open-source software as possible on your computer. Here are a few of the options:

- Gnash

- LightSpark
