Macromedia's ClosedSource vector graphics and animation format. Along with Java, it is the most common plugin installed in WebBrowsers.

Many WebComics are done in MacromediaFlash.

Often there are font problems with DebianLinux when using MacromediaFlash. Possibly Ubuntu might have the same issues also.

• install x-ttcidfont-conf package
• install msttcorefonts package
• install ttf-freefont package
• install ttf-bitstream-vera package
• install ttf-xfree86-nonfree package

Edit the file /usr/X11R6/lib/X11/fs/config and make sure you have /var/lib/defoma/x-ttcidfont-conf.d/dirs/TrueType/ path listed in the catalogue line. Restart xfs (sudo /etc/init.d/xfs restart) and restart your web-browser.

(NB The reference to X11R6 is deliberate rather than xfree as this is where MacromediaFlash looks)
