<ulink type="help" url="ghelp:musicvideophotos#music-audiostreams">Listen to online audio streams</ulink> (instructions for installing <application>RealPlayer</application>)

Multimedia codecs

Flash is a proprietary plugin which allows you to watch videos and animations on the Internet.

To view Flash graphics from the <application>Firefox Web Browser</application>:

Install the <application>flashplugin-nonfree</application> package from the <quote>Multiverse</quote> repository (see <ulink type="help" url="ghelp:add-applications">Add Applications</ulink>).

Restart <application>Firefox</application> to make the plugin available.

Java browser plugin

Some websites use small <application>Java</application> programs, which require a Java plugin to be installed in order to run.

These instructions are for <emphasis>i386</emphasis> and <emphasis>AMD64</emphasis> computers only. The plugin is not currently available for other computers.

If you are using an <emphasis>i386</emphasis> computer install the <application>sun-java5-plugin</application> package from the <quote>Multiverse</quote> repository.

If you are using an <emphasis>AMD64</emphasis> computer install the <application>j2re1.4-mozilla.plugin</application> package from the <quote>Multiverse</quote> repository.

For a more complete Java installation, see <ulink type="help" url="ghelp:programming#java">Java</ulink>.

Changing the default font size

If you find that the size of text in Firefox is too small to read comfortably, you can increase the default font size.

Press <menuchoice><guimenuitem>Edit</guimenuitem><guimenuitem>Preferences</guimenuitem></menuchoice> and select the <guilabel>Content</guilabel> tab

Under <guilabel>Fonts &amp; Colors</guilabel>, change the <guilabel>Size</guilabel> to a larger number (around 20 tends to be quite comfortable to read)

Text on web pages should immediately look larger. Press <guibutton>Close</guibutton>

To temporarily increase the size of text on a web page, press <menuchoice><guimenuitem>View</guimenuitem><guimenuitem>Text Size</guimenuitem><guimenuitem>Increase</guimenuitem></menuchoice>. Alternatively, hold down the <keycap>Ctrl</keycap> key and scroll down with your mouse's scroll wheel, or press <keycombo><keycap>Ctrl</keycap><keycap>+</keycap></keycombo>.

To return the text to its normal size, press <menuchoice><guimenuitem>View</guimenuitem><guimenuitem>Text Size</guimenuitem><guimenuitem>Normal</guimenuitem></menuchoice>.

Send and receive emails

Email is one of the most popular ways to communicate over the Internet. Ubuntu includes all of the tools that you need to send, receive and organize email messages.

The <application>Evolution</application> groupware suite is the default email client, and can handle all of your <ulink type="help" url="ghelp:evolution#usage-mail">email</ulink>, <ulink type="help" url="ghelp:evolution#usage-contact">contact lists</ulink>, <ulink type="help" url="ghelp:evolution#usage-calendar-todo">tasks</ulink> and <ulink type="help" url="ghelp:evolution#usage-calendar">calendar</ulink> needs. It also integrates with the <ulink type="help" url="ghelp:clock#clock-usage-calendar">panel clock</ulink>, giving you one-click access to your task list.

<application>Evolution</application> can be launched by pressing <menuchoice><guimenu>Applications</guimenu><guimenuitem>Internet</guimenuitem><guimenuitem>Evolution Mail</guimenuitem></menuchoice>.

See the <ulink type="help" url="ghelp:evolution">Evolution manual</ulink> for help on how to use Evolution.

Junk mail filtering

Bogofilter classifies mail as junk mail (also known as <emphasis>spam</emphasis>) by analysing the message statistically, and can learn from selections made by the user. The technique is known as Bayesian filtering; you can find more details on this here:

Evolution can be automatically configured to use Bogofilter.

Install the <application>Bogofilter</application> package (see <ulink type="help" url="ghelp:add-applications">Add Applications</ulink>)

Open <menuchoice><guimenu>Applications</guimenu><guimenuitem>Internet</guimenuitem><guimenuitem>Evolution Mail</guimenuitem></menuchoice>.

Enable the junk mail filter by selecting <menuchoice><guimenu>Edit</guimenu><guimenu>Preferences</guimenu><guimenu>Mail Preferences</guimenu><guimenu>Junk</guimenu><guimenu>Check incoming mail for junk</guimenu></menuchoice>.

Turn on the Bogofilter plugin by selecting <menuchoice><guimenu>Edit</guimenu><guimenu>Plugins</guimenu></menuchoice>

Bogofilter will now start to learn what is spam, based on the messages you mark. To mark a message as spam, select <menuchoice><guimenu>Message</guimenu><guimenu>Mark As</guimenu><guimenu>Junk</guimenu></menuchoice>.
