I installed chromium browser in my ubuntu and it works very well.

To install flash plugin for chromium browser,first we need run following to install flash.

sudo apt-get install flashplugin-nonfree

Then copy libflashplayer.so file into /usr/lib/chromium-browser/plugins directory

sudo cp /usr/lib/flashplugin-installer/libflashplayer.so /usr/lib/chromium-browser/plugins

Now,navigate to Applications–>Internet–>Chromium Web Browser and right click it, add to panel.

Right click on the icon,select Properties,type following in command field.

chromium-browser -- enable-plugins
