Swiftfox is like Firefox, but hellishly optimized for your Linux build, you can get it from...

• Go here
• Then download the installer right for your build (if 64-bit, download Athlon 64)

Once downloaded, navigate to the download in Terminal and do,

sudo sh install-swiftfox.sh

Flash

Now to get Flash running first check the ~/.mozilla/plugins directory exists on your machine, if not create it...

mkdir ~/.mozilla/plugins

Adobe only provide it as a 32-bit library but with the necessary dependency you can support it so run...

sudo aptitude install nspluginwrapper

Once you've got that you should be capable of handling the 32-bit Flash player,

...grab Flash from here

Download the .tar.gz version, extract it to your desktop, then move the libflashplayer.so into the ~/.mozilla/plugins directory,

sudo mv ~/Desktop/install_flash_player_9_linux/libflashplayer.so  ~/.mozilla/plugins

And finally restart Swiftfox, navigate to a flash video here and enjoy faster browsing with Swiftfox + Flash!
