Firefox on Debian/Ubuntu/Kubuntu and Adobe Flash Player issues
After installing Firefox 3.6 on my Kubuntu using repositories here
I removed firefox 3.5 before running the following command so you might want to use "upgrade" instead of "install" in the last command
sudo add-apt-repository ppa:mozillateam/firefox-stable sudo apt-get update sudo apt-get install firefox
I realized that it can no longer play flash contents! I did a little bit search and found this solution :
sudo apt-get remove swfdec-mozilla sudo apt-get remove mozilla-plugin-gnash sudo apt-get remove adobe-flashplugin sudo apt-get install flashplugin-nonfree
Unfortunately it didn't fix my problem so i decided to run firefox from terminal in order to see what's really wrong.
Clearly something was wrong with flash libraries :
LoadPlugin: failed to initialize shared library /home/user/.mozilla/plugins/libflashplayer.so [/home/user/.mozilla/plugins/libflashplayer.so: wrong ELF class: ELFCLASS64]
So searched the error on google and after reading several articles with no luck an idea came into my mind. [ELFCLASS64] looks like an incompatibility between 32/64 versions! i checked Firefox to make sure that i've installed the correct version Help -> About (The Textarea at the bottom of the windows) :
Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9.2) Gecko/20100218 Ubuntu/9.10 (karmic) Firefox/3.6
As you can see it's 32bit so the only thing which remains is Adobe flash libraries. So i removed the Flash libraries i installed using Ubuntu repositories and used the one from Adobe site Adobe Flash Player (Download the .tar.gz for Linux) :
extract it (it includes a single file libflashplayer.so) and then copy it to Firefox's plugin folder :
cp /home/salek/Download/libflashplayer.so . sudo cp /home/salek/Download/libflashplayer.so libflashplayer.so
If it didn't work for you i have something better , try the folowing command :
sudo apt-get install flashplugin-installer
So what really caused this issue! well no accurate answer but probably outdated repository packages.
Updated (2010-05-02) : If your flash player does not have any sound! there is an easy solution, open command line and enter
You should be able to see a volume control channel list, for no apparent reason some are muted! use the arrow keys, or your mouse's wheel, to alter them.
