Setting up firefox32 with flash plugins and avant-window-manager (OSX) on AMD64

You need to make sure that universe and multiverse repositories are enabled in your /etc/apt/sources.list before doing anything.

First we need to make sure some packages are installed.Open a terminal and enter the following:

uniks@uranium:~$ sudo apt-get install ia32-libs lib32asound2 lib32ncurses5 ia32-libs-sdl ia32-libs-gtk gsfonts gsfonts-x11 linux32

Download Firefox32 and ialib32-firefox-amd64 and enter the following command:
uniks@uranium:~$ sudo dpkg -i ia32-lib-firefox-amd64.deb firefox32-1.5.0.7-2-ubuntu-amd64.deb

Now to make sure we always run 32bit version instead of AMD64 (of course you can run your AMD64 version too if you miss it too much :P )

uniks@uranium:~$ sudo mv /usr/bin/firefox /usr/bin/firefox64
uniks@uranium:~$ sudo ln -sf /usr/local/bin/firefox32 /usr/bin/firefox

If you decide you want to run 64bit firefox, press ALT+F2 and type there firefox64 and that should get you going.

Download Flashplayer and type the following commands:

uniks@uranium:~$ tar -zxpvf install_flash_player_9_linux.tar.gz
uniks@uranium:~$ cd install_flash_player_9_linux
uniks@uranium:~$ cp -rf libflashplayer.so /usr/lib32/firefox32/plugins/
uniks@uranium:~$ cp -rf flashplayer.xpt /usr/lib32/firefox32/plugins/

Restart your browser ;)

Avant:

Note: To run this window manager, you require either Beryl or Compiz running or the visual effect is not really good with an unpleasant black shadow bar occupying the bottom of your screen.

This one is quite simple, download Avant-Window-manager and Affinity-search and issue the following commands:
uniks@uranium:~$ sudo dpkg -i avant-window-navigator_0.1.1-svn-1_amd64.deb
uniks@uranium:~$ sudo dpkg -i affinity_0.1-1_amd64.deb

After installation, make sure either Beryl or Compiz is running and run the following command after pressing ALT+F2:
avant-window-manager

This should get you the Mac OS X like window manager, you can prefferably delete the bottom panel which manages your windows ;))
