How to setup x86_64 plugins for Firefox on Centos 5
CentOS x86_64 ships with a 64-bit version of Firefox, but finding and configuring plugins can be problematic. Many people still prefer and recommend using the 32 bit version of the browser and plugins on x86_64; however, x86_64 support has improved and this page will hopefully help if one wants to go 64-bit. This page will describe how to install and configure Adobe Flash and Java plugins.
- Note: CentOS 5.3 ships with java-1.6.0-openjdk-1.6.0 but the x86_64 java-1.6.0-openjdk-plugin package is missing.
Step 1: Set up the RPMforge repo
The Wiki article AdditionalResources/Repositories describes how to configure RPMforge. Please note the warnings there, and read and follow the Wiki document Priorities to set up the yum-priorities plugin when using third party repositories.
Step 2: Set up the x86_64 flash plugin
Adobe describes the plugin as Alpha but it is known to work on various Linux systems. See the Adobe web page. The following will install an RPM package containing the plugin.
yum remove flash-plugin nspluginwrapper*yum install flash-plugin
Step 3: Set up x86_64 Java runtime and plugin
sh ./jre-6u13-linux-x64-rpm.binalternatives --install /usr/bin/java java /usr/java/jre1.6.0_13/bin/java 2alternatives --config java
The final step above depends on what other java alternatives you may have installed. Pick "/usr/java/jre1.6.0_13/bin/java".
cd /usr/lib64/mozilla/pluginsln -s /usr/java/jre1.6.0_13/lib/amd64/libnpjp2.so
Step 4: Test Java runtime and Flash plugin
java -version
Should return the Java version.
Java and flash plugins should now be working. Exit Firefox if it is running and [re]start Firefox.
Type "about:plugins" in the URL field. It should show Java and Flash enabled.
