This document was last updated for Opera 11.00.
Opera supports the standard plug-in interface on Linux, the Gecko Plugin API. Opera runs plug-ins in a separate process using an external application called operapluginwrapper. If a plug-in is misbehaving, you can kill this process without exiting Opera.
All the major Linux distributions today have excellent systems for installing and updating software, making it possible to download and install a plug-in with a simple click or command. We recommend using such a package manager to install plug-ins. However, on this page we give additional instructions for those who prefer to install the plug-in manually.
The general procedure for manual installation is the following:
Instructions for the first step are usually given by the plug-in manufacturer, and are repeated below. For the second step, there are at least two alternative procedures: either copy the plug-in to,where it will be discovered automatically after restarting Opera, or add the directory containing the plug-in to the plug-in path. To add a new directory to the plug-in path, select , click on "Plug-in options", and "Change path".
After changing the path, restart Opera, and if all went well, the plug-in should be listed under. To be certain that Opera will use the plug-in, and not some alternative application, go to , and select the mime-type associated with the plug-in. Click on "Edit", and make sure that "Use plug-in" is marked appropriately.
Note: A user without root access can install the plug-in in.

The installation instructions for Java on java.com are are correct, but the configuration step is wrong. Use the following instructions instead.
