Well the best and easiest is to use distribution packages but … some distribution have slow package updates so you need to do it your self. Here is short text how to do it.
The procedures from 1-5 are well documented here.
Creating new links for plugins
Go to new firefox dir
plugins dir does not exist do:
go to plugins dir
Create symbolic links to plugin libraries you want to use. This depends where are plugins located. From my experience it is better to use plugins which come with distribution but you can download plugins from any source (you can than expect dependency problems). In my case (OpenSUSE) plugin links are created like (you must be in
>ln -s /usr/lib/browser-plugins/javaplugin.so >ln -s /usr/lib/browser-plugins/libflashplayer.so
By default when new firefox version is ready firefox will try to update automatically. If you are regular user it won't work (update dialog will stuck downloading update) as you do not have needed file permissions.
The easiest way if to start firefox as
root and go to
Help→About. There are all options for update (usually update is started automatically) but you must be root for update to work.
Harder way is to repeat above installation procedure for new version.
