no flashplayer on 64-bit OS

[HermanAA]

I recently installed the 64-bit version of Ubuntu 8.10.
No Flash-player yet. 

I tried the Adobe Flash Player:

n0jn at bsw:~/2$ ls -l
-r-xr-xr-x 1 n0jn n0jn    21701 2008-11-19 07:53 flashplayer-installer
-rwxr-xr-x 1 n0jn n0jn 10022452 2008-11-19 07:53 libflashplayer.so
n0jn at bsw:~/2$ sudo ./flashplayer-installer

ERROR: Your architecture, \'x86_64\', is not supported by the
       Adobe Flash Player installer.

Adobe says:
TechNote
Flash Player support on 64-bit operating systems

Issue
Adobe Flash Player is not supported for playback in a 64-bit browser.
However, you can run Flash Player in a 32-bit browser running on a
64-bit operating system.

Reason
Adobe is working on Flash Player support for 64-bit platforms. We expect
to provide native support for 64-bit platforms in an upcoming release of
Flash Player following Flash Player 10.

Solution
To use Flash Player to view Flash content on a 64-bit operating system,
you must run a 32-bit browser.

My browsers are 64-bit looks like:

FireFox
Mozilla/5.0 (X11; U; Linux x86_64; en-US; rv:1.9.0.5) Gecko/2008121623
Ubuntu/8.10 (intrepid) Firefox/3.0.5

Opera/9.63 (X11; Linux x86_64; U; en) Presto/2.1.1

How can I get around this limitation?
I have to REMOVE Opera and FireFox?
(and install an old version?)
.... there must be a better way ......
