Note: Because web browser plug-ins are standardized, take a look at Firefox:Useful plug-ins for more information. The directions will work with most browsers in addition to Firefox.

Flash Player

To install Flash Player, run:

# pacman -S flashplugin

You may also need to install ttf-ms-fonts to render text properly for Flash Player:

# pacman -S ttf-ms-fonts

Troubleshooting

If plug-ins in Firefox do not work at all, check the permissions of /usr/lib/mozilla. In some cases only root may be allowed to read files.

$ cd /usr/lib/mozilla
cd: permission denied: /usr/lib/mozilla
# chmod 755 /usr/lib/mozilla
# chmod 755 /usr/lib/mozilla/extensions
Note: The user needs to logout and log back in, to start using Flash.

Performance

Adobe's Flash plug-in has some serious performance issues, specially when CPU frequency scaling is used. There seems to be a policy not to use the whole CPU workload, so the frequency scaling governor does not clock the CPU any higher. To work around this issue, see: CPUfreq:Changing the Ondemand Governor's threshold

If you have an ATI card, try disabling AIGLX by editing /etc/X11/xorg.conf:

Option "AIGLX" "False"

Configuration

To change your general plug-in preferences (privacy settings, resource usage, etc.), you have to go to the Macromedia website. There, a Flash animation will give you access to your local settings.

Adobe Reader

Due to licensing restrictions, Adobe Reader cannot be distributed from any of the normal Arch repository. There is a version available in the AUR.

There are localizations available in many languages, check the AUR for your language.

Due to a missing path you have to run:

$ ln -s /usr/share/Adobe/Reader8/bin/acroread /usr/bin

Please note that no matter how many votes it receives, this package will never be included in the [community] repository. See this comment for an explanation.
