Install Adobe Flash Player 11 beta in Linux
Update: if you use Firefox, try Flash Aid addon for easily installing the latest Adobe Flash Player (thanks to Sid32 for the tip!).
The easiest way to install Adobe Flash Player 11 beta (currently version 18.104.22.168) is to download the .tar.gz, extract it and copy the "libflashplayer.so" file into ~/.mozilla/plugins (if this folder doesn't exist, create it). This isn't just for Firefox and will also work for Chromium, Epiphany, etc.
Using this Flash Player installation method, you can also easily remove it if you want to go back to your initial Adobe Flash Player version: just remove the "libflashplayer.so" file under ~/.mozilla/plugins and restart the browser.
To get a "full installation" like tweaking Flash propreties and more, you'll have to copy the rest of the files available in the Flash Player 11 .tar.gz archive into their appropriate folders (just copy each file under the "usr" folder in the downloaded archive to the corresponding system folder. But this is not required to have a working Adobe Flash Player 11 beta.
For 64bit users, there's an Ubuntu PPA available - packages available for Ubuntu Oneiric, Natty, Maverick, Lucid, Karmic and Hardy. Add the PPA (64bit only!) and install the latest Adobe Flash Player using the commands below:
sudo add-apt-repository ppa:sevenmachines/flash sudo apt-get update sudo apt-get install flashplugin64-installer
Download Adobe Flash Player 11 beta (available for Linux, Windows and Mac OS X, both 32bit and 64bit).
