If you're using Ubuntu 9.04 or earlier, please visit the older version of this page.

Even though visiting a page that requires Flash will eventually lead you to getting the Adobe Flash plugin installed. It's better to use the Ubuntu Software Center to install it, since any future updates to the plugin will be automatically available to you.

Go to the Ubuntu Software Center

You can search directly for flash or visit the Other category.

Install it.

Authenticate with your user password.

Wait for it to install.

Before you can use the plugin, you may have to quit Firefox and then start it again.

Once you've started Firefox again, you should be able to view Flash-using websites.
