How do I enable Flash in Firefox?

Asked by tdn

After upgrading to Kubuntu 10.04, Flash does not work in Mozilla Firefox.

I have tried disabling all extensions. That did not help.

When I start Firefox from a terminal and go to a Flash site (e.g. Youtube) I see this error in the terminal:
LoadPlugin: failed to initialize shared library /home/tdn/.mozilla/plugins/libflashplayer.so [/home/tdn/.mozilla/plugins/libflashplayer.so: wrong ELF class: ELFCLASS64]

The error is repeated several times.

How to I fix this?

Seems you have installed 64bits flash on a 32bit Ubuntu system...

I just did that.

Here is the output from reinstalling the package:

When I start Firefox again, I still get this error:
LoadPlugin: failed to initialize shared library /home/tdn/.mozilla/plugins/libflashplayer.so [/home/tdn/.mozilla/plugins/libflashplayer.so: wrong ELF class: ELFCLASS64]

I noticed that this error occured several times in the logs at different addresses:

You need to remove this file or move it out of .mozilla temporarily and restart Firefox:
/home/tdn/.mozilla/plugins/libflashplayer.so
